+### Support KnockoutJS
+Include [knockout-sortable.js](knockout-sortable.js)
+
+```html
+<div data-bind="sortable: {foreach: yourObservableArray, options: {/* sortable options here */}}">
+	<!-- optional item template here -->
+</div>
+
+<div data-bind="draggable: {foreach: yourObservableArray, options: {/* sortable options here */}}">
+	<!-- optional item template here -->
+</div>
+```
+
+Using this bindingHandler sorts the observableArray when the user sorts the HTMLElements.
+
+The sortable/draggable bindingHandlers supports the same syntax as Knockouts built in [template](http://knockoutjs.com/documentation/template-binding.html) binding except for the `data` option, meaning that you could supply the name of a template or specify a separate templateEngine. The difference between the sortable and draggable handlers is that the draggable has the sortable `group` option set to `{pull:'clone',put: false}` and the `sort` option set to false by default (overridable).
+
+Other attributes are:
+*	options: an object that contains settings for the underlaying sortable, ie `group`,`handle`, events etc.
+*	collection: if your `foreach` array is a computed then you would supply the underlaying observableArray that you would like to sort here.

All modern browsers seem to support `window.pageXOffset` and `window.pageYOffset`, which are aliases for `window.scrollX` and `window.scrollY`.

IE doesn't seem to have `window.scrollX` and `window.scrollY`.

Subject: [PATCH 103/594] Correctly match multiple class names

Assume that el.className === "foo bar"
Assume that your selector is "DIV.foo.bar"

(' ' + el.className + ' ').match(re) will only have one match - " foo " - because the "\\s" trailing character on "foo" prevents " bar " from being matched

EZ fix is just to make sure the trailing whitespace is not consumed by the regex

Subject: [PATCH 107/594] fix click event for mobile devices and old browser

added forcePolyfill option.
forcePolyfill is made to make cross-browser testing more easy.
forcePolyfill provides a reliable, consistent cross-browser Solution for
Sortable.
forcePolyfill gives us the possibility to change the way "dragged items"
lok like.

+#### `forcePolyfill` option
+If set to `true`, the polyfill - or Fallback for non HTML5 Browser - will be used, even if we are using an HTML5 Browser.
+This gives us the possiblity to test the behaviour for older Browsers even in newer Browser, or make the Drag 'n Drop feel more consistent between Desktop , Mobile and old Browsers.
+
+On top of that, the polyfill always generates a copy of that DOM Element in the Document's Body. This behaviour can be exploited to give us more control over the look of this 'dragged' Element.
+
+Demo: http://jsbin.com/zejimolava/edit?html,css,js,output

 #### `scroll` option
 If set to `true`, the page (or sortable-area) scrolls when coming to an edge.

Subject: [PATCH 112/594] forceFallback changes

removed the default behaviour to append the cloned Element to the body.
now the cloned Element gets added in the same parent, with the addition
of the class defined in options.fallbackClass.
added the possibility to change the fallback class.
added the possibility to decide wheter the fallback should be cloned
into the same parent or to the document's body.

+
+    use `page{d}Offset` instead of `scroll{d}`
+
+    All modern browsers seem to support `window.pageXOffset` and `window.pageYOffset`, which are aliases for `window.scrollX` and `window.scrollY`.
+
+    IE doesn't seem to have `window.scrollX` and `window.scrollY`.

+
+    Sort event does not always fire
+
+    In the dev branch the `sort` event is not always correctly called on the receiving list. This IS working in the latest released branch. The fix is trivial and included in this PR.
+
+    The case is illustrated in this JsBin: http://jsbin.com/muxojulevo/3/edit. It occurs whenever an item is picked up from a list and dropped in a nested container.

-    use `page{d}Offset` instead of `scroll{d}`
-
-    All modern browsers seem to support `window.pageXOffset` and `window.pageYOffset`, which are aliases for `window.scrollX` and `window.scrollY`.
-
-    IE doesn't seem to have `window.scrollX` and `window.scrollY`.
-
-    fixes #302

-    Sort event does not always fire
-
-    In the dev branch the `sort` event is not always correctly called on the receiving list. This IS working in the latest released branch. The fix is trivial and included in this PR.
-
-    The case is illustrated in this JsBin: http://jsbin.com/muxojulevo/3/edit. It occurs whenever an item is picked up from a list and dropped in a nested container.

Subject: [PATCH 168/594] "distance" option

An attempt to implement the "distance" option (like http://api.jqueryui.com/sortable/#option-distance).
This is useful when your sortable element is also clickable. This prevents the drag to begin due to a micro-movement when you click.

+#### `fallbackTolerance` option
+Emulates the native drag threshold. Specify in pixels how far the mouse should move before it's considered as a drag.
+Useful if the items are also clickable like in a list of links.
+
+When the user clicks inside a sortable element, it's not uncommon for your hand to move a little between the time you press and the time you release.  
+Dragging only starts if you move the pointer past a certain tolerance, so that you don't accidentally start dragging every time you click.
+
+3 to 5 are probably good values.
+
+
+---
+
+
 #### `scroll` option
 If set to `true`, the page (or sortable-area) scrolls when coming to an edge.

Subject: [PATCH 185/594] avoid changing oldIndex by the parent container

should fix #618 and #597

oldIndex was changed first by with the item being dragged, but also by the drag event of the parent (which should be avoided when we are not using the drag-handle)

Subject: [PATCH 199/594] fix for sorting elements within a non-homogenus list
 of elements

For instance, say you are sorting tbody's within a table element.  There
can also exist tfoot and thead within the table element.  The _index()
function assumes that the list of elements within the parent is
homogenus (ie: just li's below an ol/ul).  This isnt the case when
sorting tbody under table.  This is edge case until you want to group
tr's under a table and sort on those groupings.

Subject: [PATCH 200/594] refactor _matches() out of _closest()

The _closest() method already defined a way to do what _matches() was
trying to accomplish.  This pulls the functionality out of _closest() so
that it can be reused outside of _closest() but refactors _closest() to
use this new _matches() method.

Subject: [PATCH 204/594] Sometimes evt.from is different from
 evt.item.parentNode because the item has been moved already so using
 evt.item.nextSibling won't work when doing evt.from.insertBefore, because
 nextSibling is not a child of evt.from.

So in those cases we use evt.clone.nextSibling instead.

Subject: [PATCH 220/594] Allow event functions to be defined as functions AND
 strings.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current behavior (in `master`) is to define the handling functions for events as strings. Default for `onSort` for example is `handleSort`. Commit 8cef762d11dbabb27e489727bcc8fd5dfe8d844d changed this behavior forcing handling functions to be defined as functions in the options. This breaks all existing code, resulting in a no-op even with the default options (which still define the default handlers as strings).

This commit restores previous behavior AND allows you to define your handlers as functions directly, if you’re so inclined.

-Reactive reorderable lists with [Sortable](http://rubaxa.github.io/Sortable/),
-backed by [Meteor.js](http://meteor.com) collections:
-
-* new elements arriving in the collection will update the list as you expect
-* elements removed from the collection will be removed from the list
-* drag and drop between lists updates collections accordingly
-
-Demo: http://rubaxa-sortable.meteor.com
-
-# Meteor
-
-If you're new to Meteor, here's what the excitement is all about -
-[watch the first two minutes](https://www.youtube.com/watch?v=fsi0aJ9yr2o); you'll be hooked by 1:28.
-That screencast is from 2012. In the meantime, Meteor has become a mature JavaScript-everywhere web
-development framework. Read more at [Why Meteor](http://wiki.dandascalescu.com/essays/why_meteor).
-
-
-# Usage
-
-Simplest invocation - order will be lost when the page is refreshed:
-
-```handlebars
-{{#sortable <collection|cursor|array>}}
-```
-
-Persist the sort order in the 'order' field of each document in the collection:
-
-*Client:*
-
-```handlebars
-{{#sortable items=<collection|cursor|array> sortField="order"}}
-```
-
-*Server:*
-
-```js
-Sortable.collections = <collectionName>;  // the name, not the variable
-```
-
-Along with `items`, `sortField` is the only Meteor-specific option. If it's missing, the package will
-assume there is a field called "order" in the collection, holding unique `Number`s such that every
-`order` differs from that before and after it by at least 1. Basically, keep to 0, 1, 2, ... .
-Try not to depend on a particular format for this field; it *is* though guaranteed that a `sort` will
-produce lexicographical order, and that the order will be maintained after an arbitrary number of
-reorderings, unlike with [naive solutions](http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible).
-
-Remember to declare on the server which collections you want to be reorderable from the client.
-Otherwise, the library will error because the client would be able to modify numerical fields in
-any collection, which represents a security risk.
-
-
-## Passing options to the Sortable library
-
-    {{#sortable items=<collection|cursor|array> option1=value1 option2=value2...}}
-    {{#sortable items=<collection|cursor|array> options=myOptions}}
-
-For available options, please refer to [the main README](../README.md#options). You can pass them directly
-or under the `options` object. Direct options (`key=value`) override those in `options`. It is best
-to pass presentation-related options directly, and functionality-related settings in an `options`
-object, as this will enable designers to work without needing to inspect the JavaScript code:
-
-    <template name="myTemplate">
-      ...
-      {{#sortable items=Players handle=".sortable-handle" ghostClass="sortable-ghost" options=playerOptions}}
-    </template>
-
-Define the options in a helper for the template that calls Sortable:
-
-```js
-Template.myTemplate.helpers({
-    playerOptions: function () {
-        return {
-            group: {
-                name: "league",
-                pull: true,
-                put: false
-            },
-            sort: false
-        };
-    }
-});
-```
-
-#### Meteor-specific options
-
-* `selector` - you can specify a collection selector if your list operates only on a subset of the collection. Example:
-
-```js
-Template.myTemplate.helpers({
-   playerOptions: function() {
-      return {
-         selector: { city: 'San Francisco' }
-      }
-   }
-});
-```
-
-
-## Events
-
-All the original Sortable events are supported. In addition, they will receive
-the data context in `event.data`. You can access `event.data.order` this way:
-
-```handlebars
-{{#sortable items=players options=playersOptions}}
-```
-
-```js
-Template.myTemplate.helpers({
-    playersOptions: function () {
-        return {
-            onSort: function(/**Event*/event) {
-                console.log('Moved player #%d from %d to %d',
-                    event.data.order, event.oldIndex, event.newIndex
-                );
-            }
-        };
-    }
-});
-```

-# RubaXa:Sortable Meteor demo
-
-This demo showcases the two-way integration between the reorderable list
-widget [Sortable](https://github.com/RubaXa/Sortable/) and Meteor.js. Meteor
-Mongo collections are updated when items are added, removed or reordered, and
-the order is persisted.
-
-It also shows list grouping and control over what lists can give or receive
-elements. You can only drag elements from the list to the left onto the list
-to the right.
-
-
-## Usage
-
-The example uses the local package from the checkout, with the help of the run script:
-
-### Windows
-
-    git clone https://github.com/RubaXa/Sortable.git
-    cd Sortable
-    # git checkout dev  # optional
-    meteor\example\run.bat
-
-### Elsewhere
-
-    git clone https://github.com/RubaXa/Sortable.git
-    cd Sortable
-    # git checkout dev  # optional
-    meteor/example/run.sh
-
-
-## [Prior art](http://slides.com/dandv/prior-art)
-
-### Differential
-
-Differential wrote [a blog post on reorderable lists with
-Meteor](http://differential.com/blog/sortable-lists-in-meteor-using-jquery-ui) and
-[jQuery UI Sortable](http://jqueryui.com/sortable/). It served as inspiration
-for integrating [rubaxa:sortable](rubaxa.github.io/Sortable/),
-which uses the HTML5 native drag&drop API (not without [its
-limitations](https://github.com/RubaXa/Sortable/issues/106)).
-The reordering method used by the Differential example can lead to data loss
-though, because it calculates the new order of a dropped element as the
-arithmetic mean of the elements before and after it. This [runs into limitations
-of floating point precision](http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible)
-in JavaScript after <50 reorderings.
-
-### Todos animated
-
-http://todos-dnd-animated.meteor.com/ ([source](https://github.com/nleush/meteor-todos-sortable-animation))
-is based on old Meteor Blaze (back then Spark) API, and won't work with current versions.
-It does showcase some neat features, such as animation when collection elements
-are reordered by another client. It uses jQuery UI Sortable as well, which lacks
-some features vs. rubaxa:Sortable, e.g. text selection within the item.
-
-## TODO
-
-* Animation
-* Indication that an item is being edited

-	 *    element to the average of the orders of the elements around it -
-	 *    http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible
-	 *    The downside is that the order field in the DB will increase by one byte every
-	 *    time an element is reordered.
-	 * 2) Adjust the orders of the intervening items. This keeps the orders sane (integers)
-	 *    but is slower because we have to modify multiple documents.
-	 *    TODO: we may be able to update fewer records by only altering the
-	 *    order of the records between the newIndex/oldIndex and the start/end of the list.
-	 * 3) Use regular precision arithmetic, but when the difference between the orders of the
-	 *    moved item and the one before/after it falls below a certain threshold, adjust
-	 *    the order of that other item, and cascade doing so up or down the list.
-	 *    This will keep the `order` field constant in size, and will only occasionally
-	 *    require updating the `order` of other records.
-	 *
-	 * For now, we use approach #2.
-	 *
-	 * @param {String} itemId - the _id of the item that was moved
-	 * @param {Number} orderPrevItem - the order of the item before it, or null
-	 * @param {Number} orderNextItem - the order of the item after it, or null

Currently it is not possible to re-initialize the sortable component after it's been destroyed. I've added a method and wrapped everything in the attached in there and instead I'm calling that method on attached.

Subject: [PATCH 256/594] knockout: run deferred tasks early

If `ko.options.deferUpdates = true`, then updates to the UI don't happen immediately when you modify the viewModel.
For the sortable binding, this means that after removing a moved item, it doesn't recreate it at the new position.
Calling `ko.tasks.runEarly` before re-inserting the item into the observableArray makes KO register the removal.

This is the fix proposed by @adriaanmeuris in RubaXa/Sortable#712

-### Support KnockoutJS
-Include [knockout-sortable.js](knockout-sortable.js)
-
-```html
-<div data-bind="sortable: {foreach: yourObservableArray, options: {/* sortable options here */}}">
-	<!-- optional item template here -->
-</div>
-
-<div data-bind="draggable: {foreach: yourObservableArray, options: {/* sortable options here */}}">
-	<!-- optional item template here -->
-</div>
-```
-
-Using this bindingHandler sorts the observableArray when the user sorts the HTMLElements.
-
-The sortable/draggable bindingHandlers supports the same syntax as Knockouts built in [template](http://knockoutjs.com/documentation/template-binding.html) binding except for the `data` option, meaning that you could supply the name of a template or specify a separate templateEngine. The difference between the sortable and draggable handlers is that the draggable has the sortable `group` option set to `{pull:'clone',put: false}` and the `sort` option set to false by default (overridable).
-
-Other attributes are:
-*	options: an object that contains settings for the underlaying sortable, ie `group`,`handle`, events etc.
-*	collection: if your `foreach` array is a computed then you would supply the underlaying observableArray that you would like to sort here.
-*   manuallyHandleUpdateEvents: a boolean to turn off the change events on update that other polymer elements listen to.

-Reactive reorderable lists with [Sortable](http://rubaxa.github.io/Sortable/),
-backed by [Meteor.js](http://meteor.com) collections:
-
-* new elements arriving in the collection will update the list as you expect
-* elements removed from the collection will be removed from the list
-* drag and drop between lists updates collections accordingly
-
-Demo: http://rubaxa-sortable.meteor.com
-
-# Meteor
-
-If you're new to Meteor, here's what the excitement is all about -
-[watch the first two minutes](https://www.youtube.com/watch?v=fsi0aJ9yr2o); you'll be hooked by 1:28.
-That screencast is from 2012. In the meantime, Meteor has become a mature JavaScript-everywhere web
-development framework. Read more at [Why Meteor](http://wiki.dandascalescu.com/essays/why_meteor).
-
-
-# Usage
-
-Simplest invocation - order will be lost when the page is refreshed:
-
-```handlebars
-{{#sortable <collection|cursor|array>}}
-```
-
-Persist the sort order in the 'order' field of each document in the collection:
-
-*Client:*
-
-```handlebars
-{{#sortable items=<collection|cursor|array> sortField="order"}}
-```
-
-*Server:*
-
-```js
-Sortable.collections = <collectionName>;  // the name, not the variable
-```
-
-Along with `items`, `sortField` is the only Meteor-specific option. If it's missing, the package will
-assume there is a field called "order" in the collection, holding unique `Number`s such that every
-`order` differs from that before and after it by at least 1. Basically, keep to 0, 1, 2, ... .
-Try not to depend on a particular format for this field; it *is* though guaranteed that a `sort` will
-produce lexicographical order, and that the order will be maintained after an arbitrary number of
-reorderings, unlike with [naive solutions](http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible).
-
-Remember to declare on the server which collections you want to be reorderable from the client.
-Otherwise, the library will error because the client would be able to modify numerical fields in
-any collection, which represents a security risk.
-
-
-## Passing options to the Sortable library
-
-    {{#sortable items=<collection|cursor|array> option1=value1 option2=value2...}}
-    {{#sortable items=<collection|cursor|array> options=myOptions}}
-
-For available options, please refer to [the main README](../README.md#options). You can pass them directly
-or under the `options` object. Direct options (`key=value`) override those in `options`. It is best
-to pass presentation-related options directly, and functionality-related settings in an `options`
-object, as this will enable designers to work without needing to inspect the JavaScript code:
-
-    <template name="myTemplate">
-      ...
-      {{#sortable items=Players handle=".sortable-handle" ghostClass="sortable-ghost" options=playerOptions}}
-    </template>
-
-Define the options in a helper for the template that calls Sortable:
-
-```js
-Template.myTemplate.helpers({
-    playerOptions: function () {
-        return {
-            group: {
-                name: "league",
-                pull: true,
-                put: false
-            },
-            sort: false
-        };
-    }
-});
-```
-
-#### Meteor-specific options
-
-* `selector` - you can specify a collection selector if your list operates only on a subset of the collection. Example:
-
-```js
-Template.myTemplate.helpers({
-   playerOptions: function() {
-      return {
-         selector: { city: 'San Francisco' }
-      }
-   }
-});
-```
-
-
-## Events
-
-All the original Sortable events are supported. In addition, they will receive
-the data context in `event.data`. You can access `event.data.order` this way:
-
-```handlebars
-{{#sortable items=players options=playersOptions}}
-```
-
-```js
-Template.myTemplate.helpers({
-    playersOptions: function () {
-        return {
-            onSort: function(/**Event*/event) {
-                console.log('Moved player #%d from %d to %d',
-                    event.data.order, event.oldIndex, event.newIndex
-                );
-            }
-        };
-    }
-});
-```

-# RubaXa:Sortable Meteor demo
-
-This demo showcases the two-way integration between the reorderable list
-widget [Sortable](https://github.com/RubaXa/Sortable/) and Meteor.js. Meteor
-Mongo collections are updated when items are added, removed or reordered, and
-the order is persisted.
-
-It also shows list grouping and control over what lists can give or receive
-elements. You can only drag elements from the list to the left onto the list
-to the right.
-
-
-## Usage
-
-The example uses the local package from the checkout, with the help of the run script:
-
-### Windows
-
-    git clone https://github.com/RubaXa/Sortable.git
-    cd Sortable
-    # git checkout dev  # optional
-    meteor\example\run.bat
-
-### Elsewhere
-
-    git clone https://github.com/RubaXa/Sortable.git
-    cd Sortable
-    # git checkout dev  # optional
-    meteor/example/run.sh
-
-
-## [Prior art](http://slides.com/dandv/prior-art)
-
-### Differential
-
-Differential wrote [a blog post on reorderable lists with
-Meteor](http://differential.com/blog/sortable-lists-in-meteor-using-jquery-ui) and
-[jQuery UI Sortable](http://jqueryui.com/sortable/). It served as inspiration
-for integrating [rubaxa:sortable](rubaxa.github.io/Sortable/),
-which uses the HTML5 native drag&drop API (not without [its
-limitations](https://github.com/RubaXa/Sortable/issues/106)).
-The reordering method used by the Differential example can lead to data loss
-though, because it calculates the new order of a dropped element as the
-arithmetic mean of the elements before and after it. This [runs into limitations
-of floating point precision](http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible)
-in JavaScript after <50 reorderings.
-
-### Todos animated
-
-http://todos-dnd-animated.meteor.com/ ([source](https://github.com/nleush/meteor-todos-sortable-animation))
-is based on old Meteor Blaze (back then Spark) API, and won't work with current versions.
-It does showcase some neat features, such as animation when collection elements
-are reordered by another client. It uses jQuery UI Sortable as well, which lacks
-some features vs. rubaxa:Sortable, e.g. text selection within the item.
-
-## TODO
-
-* Animation
-* Indication that an item is being edited

-	 * When an element was moved, adjust its orders and possibly the order of

-	 *    element to the average of the orders of the elements around it -
-	 *    http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible
-	 *    The downside is that the order field in the DB will increase by one byte every
-	 *    time an element is reordered.
-	 * 2) Adjust the orders of the intervening items. This keeps the orders sane (integers)
-	 *    but is slower because we have to modify multiple documents.
-	 *    TODO: we may be able to update fewer records by only altering the
-	 *    order of the records between the newIndex/oldIndex and the start/end of the list.
-	 * 3) Use regular precision arithmetic, but when the difference between the orders of the
-	 *    moved item and the one before/after it falls below a certain threshold, adjust
-	 *    the order of that other item, and cascade doing so up or down the list.
-	 *    This will keep the `order` field constant in size, and will only occasionally
-	 *    require updating the `order` of other records.
-	 *
-	 * For now, we use approach #2.
-	 *
-	 * @param {String} itemId - the _id of the item that was moved
-	 * @param {Number} orderPrevItem - the order of the item before it, or null
-	 * @param {Number} orderNextItem - the order of the item after it, or null

-### Support React ES2015 / TypeScript syntax
-As mixins are not supported in ES2015 / TypeScript syntax here is example of ES2015 ref based implementation.
-Using refs is the preferred (by facebook) "escape hatch" to underlaying DOM nodes: [React: The ref Callback Attribute](https://facebook.github.io/react/docs/more-about-refs.html#the-ref-callback-attribute)

Subject: [PATCH 293/594] Fix problem with supporting css pointer-event in IE11
 #920

IE-11 supports css pointer-events incorrect:
if your draggable elem contains pseudoelements,
Sortable.js will solve that your draggable elem
are dropping to itself.
So Sortable.js will place your draggable elem to end of list.

This PR let to Sortable.js solve that IE11 doesnt support pointer-events

Subject: [PATCH 327/594] fix: make drag on touch work in scrollable element

With Chrome version 56 the passive capture option in addEventListener defaults to true instead of false which causes dragging on touch devices to simultaneously also scroll.
Tested on Android Chrome, and device mode in Edge, Chrome and Firefox.

+#### `touchMoveSensitivity` option
+This option is similar to `fallbackTolerance` option.
+
+When the `delay` option is set, some phones with very sensitive touch displays like the Samsung Galaxy S8 will fire 
+unwanted touchmove events even when your finger is not moving, resulting in the sort not triggering.
+
+This option sets the minimum pointer movement that must occur before the delayed sorting is cancelled.
+
+Values between 3 to 5 are good.
+
+
+---
+
+
 #### `disabled` options
 Disables the sortable if set to `true`.

 Useful if the items are also clickable like in a list of links.
 
-When the user clicks inside a sortable element, it's not uncommon for your hand to move a little between the time you press and the time you release.  
+When the user clicks inside a sortable element, it's not uncommon for your hand to move a little between the time you press and the time you release.
 Dragging only starts if you move the pointer past a certain tolerance, so that you don't accidentally start dragging every time you click.
 
 3 to 5 are probably good values.

Subject: [PATCH 408/594] Added autoscroll revamp

In short, this revamp allows for elements that are parents of the currently hovered element to also autoscroll.

For native DnD, it autoscrolls the parents, but does not autoscroll the hovered element, as this is handled by HTML5.

-### jQuery compatibility
-To assemble plugin for jQuery, perform the following steps:
-
-```bash
-  cd Sortable
-  npm install
-  grunt jquery
-```
-
-Now you can use `jquery.fn.sortable.js`:<br/>
-(or `jquery.fn.sortable.min.js` if you run `grunt jquery:min`)
-
-```js
-  $("#list").sortable({ /* options */ }); // init
-
-  $("#list").sortable("widget"); // get Sortable instance
-
-  $("#list").sortable("destroy"); // destroy Sortable instance
-
-  $("#list").sortable("{method-name}"); // call an instance method
-
-  $("#list").sortable("{method-name}", "foo", "bar"); // call an instance method with parameters
-```
-
-And `grunt jquery:mySortableFunc` → `jquery.fn.mySortableFunc.js`

 #### `dragoverBubble` option
-If set to `true`, the dragover event will bubble to parent Sortables. Useful for nested Sortables. Works on both fallback and native dragover event.
+If set to `true`, the dragover event will bubble to parent sortables. Works on both fallback and native dragover event.
+By default, it is false, but Sortable will only stop bubbling the event once the element has been inserted into a parent Sortable, or *can* be inserted into a parent Sortable, but isn't at that specific time (due to animation, etc).
+
+Since 1.8.0, you will probably want to leave this option as false. Before 1.8.0, it may need to be `true` for nested sortables to work.
+
+
+---
+
+
+#### `removeCloneOnHide` option
+If set to `false`, the clone is hidden by having it's CSS `display` property set to `none`.
+By default, this option is `true`, meaning Sortable will remove the cloned element from the DOM when it is supposed to be hidden.

+## AutoScroll
+This plugin allows for the page to automatically scroll during dragging near a scrollable element's edge on mobile devices and IE9 (or whenever fallback is enabled), and also enhances most browser's native drag-and-drop autoscrolling.
+Demo:
+ - `window`: https://jsbin.com/dosilir/edit?js,output
+ - `overflow: hidden`: https://jsbin.com/xecihez/edit?html,js,output
+
+**This plugin is a default plugin, and is included in the default UMD and ESM builds of Sortable**
+
+
+---
+
+
+### Options
+
+```js
+new Sortable(el, {
+	scroll: true, // Enable the plugin. Can be HTMLElement.
+	scrollFn: function(offsetX, offsetY, originalEvent, touchEvt, hoverTargetEl) { ... }, // if you have custom scrollbar scrollFn may be used for autoscrolling
+	scrollSensitivity: 30, // px, how near the mouse must be to an edge to start scrolling.
+	scrollSpeed: 10, // px, speed of the scrolling
+	bubbleScroll: true // apply autoscroll to all parent elements, allowing for easier movement
+});
+```
+
+
+---
+
+
+#### `scroll` option
+Enables the plugin. Defaults to `true`. May also be set to an HTMLElement which will be where autoscrolling is rooted.
+
+Demo:
+ - `window`: https://jsbin.com/dosilir/edit?js,output
+ - `overflow: hidden`: https://jsbin.com/xecihez/edit?html,js,output
+
+
+---
+
+
+#### `scrollFn` option
+Defines function that will be used for autoscrolling. el.scrollTop/el.scrollLeft is used by default.
+Useful when you have custom scrollbar with dedicated scroll function.
+This function should return `'continue'` if it wishes to allow Sortable's native autoscrolling.
+
+
+---
+
+
+#### `scrollSensitivity` option
+Defines how near the mouse must be to an edge to start scrolling.
+
+
+---
+
+
+#### `scrollSpeed` option
+The speed at which the window should scroll once the mouse pointer gets within the `scrollSensitivity` distance.
+
+
+---
+
+
+#### `bubbleScroll` option
+If set to `true`, the normal `autoscroll` function will also be applied to all parent elements of the element the user is dragging over.
+
+Demo: https://jsbin.com/kesewor/edit?html,js,output

+## MultiDrag Plugin
+This plugin allows users to select multiple items within a sortable at once, and drag them as one item.
+Once placed, the items will unfold into their original order, but all beside eachother at the new position.
+[Read More](https://github.com/SortableJS/Sortable/wiki/Dragging-Multiple-Items-in-Sortable)
+
+Demo: https://jsbin.com/wopavom/edit?js,output
+
+
+---
+
+
+### Options
+
+```js
+new Sortable(el, {
+	multiDrag: false, // Enable the plugin
+	selectedClass: "sortable-selected", // Class name for selected item
+	multiDragKey: null, // Key that must be down for items to be selected
+
+	// Called when an item is selected
+	onSelect: function(/**Event*/evt) {
+		evt.item // The selected item
+	},
+
+	// Called when an item is deselected
+	onDeselect: function(/**Event*/evt) {
+		evt.item // The deselected item
+	}
+});
+```
+
+
+---
+
+
+#### `multiDragKey` option
+The key that must be down for multiple items to be selected. The default is `null`, meaning no key must be down.
+For special keys, such as the <kbd>CTRL</kbd> key, simply specify the option as `'CTRL'` (casing does not matter).
+
+
+---
+
+
+#### `selectedClass` option
+Class name for the selected item(s) if multiDrag is enabled. Defaults to `sortable-selected`.
+
+```css
+.selected {
+  background-color: #f9c7c8;
+  border: solid red 1px;
+}
+```
+
+```js
+Sortable.create(list, {
+  multiDrag: true,
+  selectedClass: "selected"
+});
+```
+
+
+---
+
+
+### Event Properties
+ - items:`HTMLElement[]` - Array of selected items, or empty
+ - clones:`HTMLElement[]` - Array of clones, or empty
+
+
+---
+
+
+### Sortable.utils
+* select(el`:HTMLElement`) — select the given multi-drag item
+* deselect(el`:HTMLElement`) — deselect the given multi-drag item

+# OnSpill Plugins
+This file contains two seperate plugins, RemoveOnSpill and RevertOnSpill. They can be imported individually, or the default export (an array of both plugins) can be passed to `Sortable.mount` as well.
+
+**These plugins are default plugins, and are included in the default UMD and ESM builds of Sortable**
+
+---
+
+
+## RevertOnSpill Plugin
+This plugin, when enabled, will cause the dragged item to be reverted to it's original position if it is spilled (ie. it is dropped outside of a valid Sortable drop target)
+
+
+---
+
+
+### Options
+
+```js
+new Sortable(el, {
+	revertOnSpill: false // Enable plugin
+});
+```
+
+
+---
+
+
+## RemoveOnSpill Plugin
+This plugin, when enabled, will cause the dragged item to be removed from the DOM if it is spilled (ie. it is dropped outside of a valid Sortable drop target)
+
+
+---
+
+
+### Options

+# Creating Sortable Plugins
+Sortable plugins are plugins that can be directly mounted to the Sortable class. They are a powerful way of modifying the default behaviour of Sortable beyond what simply using events alone allows. To mount your plugin to Sortable, it must pass a constructor function to the `Sortable.mount` function. This constructor function will be called (with the `new` keyword in front of it) whenever a Sortable instance with your plugin enabled is initialized. The constructor function will be called with the parameters `sortable` and `el`, which is the HTMLElement that the Sortable is being initialized on. This means that there will be a new instance of your plugin each time it is enabled in a Sortable.
+
+
+## Constructor Parameters
+
+`sortable: Sortable` — The sortable that the plugin is being initialized on
+
+`el: HTMLElement` — The element that the sortable is being initialized on
+
+
+## Static Properties
+The constructor function passed to `Sortable.mount` may contain several static properties and methods. The following static properties may be defined:
+
+`pluginName: String` (Required)
+The name of the option that the user will use in their sortable's options to enable the plugin. Should start with a lower case and be camel-cased. For example: `'multiDrag'`. This is also the property name that the plugin's instance will be under in a sortable instance (ex. `sortableInstance.multiDrag`).
+
+`utils: Object`
+Object containing functions that will be added to the `Sortable.utils` default object on the Sortable class.
+
+`eventOptions(eventName: String, sortable: Sortable): Function`
+A function that is called whenever Sortable fires an event. This function should return an object to be combined with the event object that Sortable will emit.
+
+`initializeByDefault: Boolean`
+Determines whether or not the plugin will always be initialized on every new Sortable instance. If this option is enabled, it does not mean that by default the plugin will be enabled on the Sortable - this must still be done in the options via the plugin's `pluginName`, or it can be enabled by default if your plugin specifies it's pluginName as a default option that is truthy. Since the plugin will already be initialized on every Sortable instance, it can also be enabled dynamically via `sortableInstance.option('pluginName', true)`.
+It is a good idea to have this option set to `false` if the plugin modifies the behaviour of Sortable in such a way that enabling or disabling the plugin dynamically could cause it to break. Likewise, this option should be disabled if the plugin should only be instantiated on Sortables in which that plugin is enabled.
+This option defaults to `true`.
+
+`optionListeners: Object`
+An object that may contain event listeners that are fired when a specific option is updated.
+These listeners are useful because the user's provided options are not necessarily unchanging once the plugin is initialized, and could be changed dynamically via the `option()` method.
+The listener will be fired in the context of the instance of the plugin that it is being changed in (ie. the `this` keyword will be the instance of your plugin).
+The name of the method should match the name of the option it listens for. The new value of the option will be passed in as an argument, and any returned value will be what the option is stored as. If no value is returned, the option will be stored as the value the user provided.
+
+Example:
+
+```js
+Plugin.name = 'generateTitle';
+Plugin.optionModifiers = {
+	// Listen for option 'generateTitle'
+	generateTitle: function(title) {
+		// Store the option in all caps
+		return title.toUpperCase();
+
+		// OR save it to this instance of your plugin as a private field.
+		// This way it can be accessed in events, but will not modify the user's options.
+		this.titleAllCaps = title.toUpperCase();
+	}
+};
+
+``` 
+
+## Plugin Options
+Plugins may have custom options or override the defaults of certain options. In order to do this, there must be an `options` object on the initialized plugin. This can be set in the plugin's prototype, or during the initialization of the plugin (when the `el` is available). For example:
+
+```js
+function myPlugin(el) {
+	this.options = {
+		color: el.style.backgroundColor
+	};
+}
+
+Sortable.mount(myPlugin);
+```
+
+
+## Plugin Events
+
+### Context
+The events will be fired in the context of their own parent object, however the plugin instance's Sortable instance is available under `this.sortable`.
+
+### Event List
+The following table contains details on the events that a plugin may handle in the prototype of the plugin's constructor function.
+
+| Event Name                | Description                                                                                                      | Cancelable? | Cancel Behaviour                                   | Event Type | Custom Event Object Properties                                          |

+
+### Global Events
+Normally, an event will only be fired in a plugin if the plugin is enabled on the Sortable from which the event is being fired. However, it sometimes may be desirable for a plugin to listen in on an event from Sortables in which it is not enabled on. This is possible with global events. For an event to be global, simply add the suffix 'Global' to the event's name (casing matters) (eg. `dragStartGlobal`).
+Please note that your plugin must be initialized on any Sortable from which it expects to recieve events, and that includes global events. In other words, you will want to keep the `initializeByDefault` option as it's default `true` value if your plugin needs to recieve events from Sortables it is not enabled on.
+Please also note that if both normal and global event handlers are set, the global event handler will always be fired before the regular one.
+
+### Event Object
+An object with the following properties is passed as an argument to each plugin event when it is fired.
+
+#### Properties:
+
+`dragEl: HTMLElement` — The element being dragged
+
+`parentEl: HTMLElement` — The element that the dragged element is currently in
+
+`ghostEl: HTMLElement|undefined` — If using fallback, the element dragged under the cursor (undefined until after `dragStarted` plugin event)
+
+`rootEl: HTMLElement` — The element that the dragged element originated from
+
+`nextEl: HTMLElement` — The original next sibling of dragEl
+
+`cloneEl: HTMLElement|undefined` — The clone element (undefined until after `setupClone` plugin event)
+
+`cloneHidden: Boolean` — Whether or not the clone is hidden
+
+`dragStarted: Boolean` — Boolean indicating whether or not the dragStart event has fired
+
+`putSortable: Sortable|undefined` — The element that dragEl is dragged into from it's root, otherwise undefined 
+
+`activeSortable: Sortable` — The active Sortable instance
+
+`originalEvent: Event` — The original HTML event corresponding to the Sortable event
+
+`oldIndex: Number` — The old index of dragEl
+
+`oldDraggableIndex: Number` — The old index of dragEl, only counting draggable elements
+
+`newIndex: Number` — The new index of dragEl
+
+`newDraggableIndex: Number` — The new index of dragEl, only counting draggable elements
+
+
+#### Methods:
+
+`cloneNowHidden()` — Function to be called if the plugin has hidden the clone
+
+`cloneNowShown()` — Function to be called if the plugin has shown the clone
+
+`hideGhostForTarget()` — Hides the fallback ghost element if CSS pointer-events are not available. Call this before using document.elementFromPoint at the mouse position.
+
+`unhideGhostForTarget()` — Unhides the ghost element. To be called after `hideGhostForTarget()`.
+
+`dispatchSortableEvent(eventName: String)` — Function that can be used to emit an event on the current sortable while sorting, with all usual event properties set (eg. indexes, rootEl, cloneEl, originalEvent, etc.).
+
+
+### DragOverEvent Object
+This event is passed to dragover events, and extends the normal event object.
+
+#### Properties:
+
+`isOwner: Boolean` — Whether or not the dragged over sortable currently contains the dragged element
+
+`axis: String` — Direction of the dragged over sortable, `'vertical'` or `'horizontal'`
+
+`revert: Boolean` — Whether or not the dragged element is being reverted to it's original position from another position
+
+`dragRect: DOMRect` — DOMRect of the dragged element
+
+`targetRect: DOMRect` — DOMRect of the target element
+
+`canSort: Boolean` — Whether or not sorting is enabled in the dragged over sortable
+
+`fromSortable: Sortable` — The sortable that the dragged element is coming from
+
+`target: HTMLElement` — The sortable item that is being dragged over
+
+
+#### Methods:
+
+`onMove(target: HTMLElement, after: Boolean): Boolean|Number` — Calls the `onMove` function the user specified in the options
+
+`changed()` — Fires the `onChange` event with event properties preconfigured
+
+`completed(insertion: Boolean)` — Should be called when dragover has "completed", meaning bubbling should be stopped. If `insertion` is `true`, Sortable will treat it as if the dragged element was inserted into the sortable, and hide/show clone, set ghost class, animate, etc.

+## Swap Plugin
+This plugin modifies the behaviour of Sortable to allow for items to be swapped with eachother rather than sorted. Once dragging starts, the user can drag over other items and there will be no change in the elements. However, the item that the user drops on will be swapped with the originally dragged item.
+
+Demo: https://jsbin.com/yejehog/edit?html,js,output
+
+
+---
+
+
+### Options
+
+```js
+new Sortable(el, {
+	swap: false, // Enable swap mode
+	swapClass: "sortable-swap-highlight" // Class name for swap item (if swap mode is enabled)
+});
+```
+
+
+---
+
+
+#### `swapClass` option
+Class name for the item to be swapped with, if swap mode is enabled. Defaults to `sortable-swap-highlight`.
+
+```css
+.highlighted {
+  background-color: #9AB6F1;
+}
+```
+
+```js
+Sortable.create(list, {
+  swap: true,
+  swapClass: "highlighted"
+});
+```
+
+
+---
+
+
+### Event Properties
+ - swapItem:`HTMLElement|undefined` - The element that the dragged element was swapped with

Subject: [PATCH 522/594] Added type check for 'dragStarted' variable as this
 is causing thousands of console errors in Chrome, Firefox, Edge, IE, Safari
 before the first drag. This change is harmless because it is just checking if
 the variable dragStarted is declared before using it.

Tested across all of the above browsers and working fine after this change.

Subject: [PATCH 530/594] Solves "inser Before" issue on nested lists
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

That solves an issue with nested sortables.
example of error https://codepen.io/romualdogrillo/pen/jOPoRJe
An error appears when all following conditions are met:
1)You have two nested sortable containers
2)option “pull:clone” i set at least on the parent container
3)You drag an item from the parent container into the nested container

The item is moved but not cloned and you get the error:
“Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted”

+#### `forceAutoScrollFallback` option
+Enables sortable's autoscroll even when the browser can handle it (with native drag and drop). Defaults to `false`. This will not disable the native autoscrolling. Note that setting `forceFallback: true` in the sortable options will also enable this.

 #### `scrollFn` option
 Useful when you have custom scrollbar with dedicated scroll function.
 Defines a function that will be used for autoscrolling. Sortable uses el.scrollTop/el.scrollLeft by default. Set this option if you wish to handle it differently.

 draggable elements at the end of the list

When dragging an element to the end of the list, and existing non draggable elements at the end of the list.  Appending it to the end of the list is not incorrect, It should be inserted before the next sibling of the last draggable element.

even if the item is dropped back into its original placement. This
means that whenever the "ignore next click" handling is activated, the
user's _next_ click (unrelated to dragging) will be ignored.

This commit solves this by never activating the "ignore next click"
handling on Android Chrome.
