+# ui.item.sortable API documentation
+
+This refers to the additional properties that are exposed through the `ui` parameter in the provided callback hooks. eg:
+```js
+$scope.sortableOptions = {
+  update: function(e, ui) {
+    if (ui.item.sortable.model == "can't be moved") {
+      ui.item.sortable.cancel();
+    }
+  }
+};
+```
+
+## Properties
+
+**Note:**
+The properties of `ui.item.sortable` object are cleared right after the stop callback fires. If you need to access them after the sorting ends, you should keep references in separate variables in your code.
+
+### dropindex
+Type: [Integer](http://api.jquery.com/Types/#Integer)  
+Holds the index of the drop target that the dragged item was dropped.
+
+
+### droptarget
+Type: [jQuery](http://api.jquery.com/Types/#jQuery)  
+Holds the ui-sortable element that the dragged item was dropped on.
+
+### droptargetModel
+Type: [Array](http://api.jquery.com/Types/#Array)  
+Holds the array that is specified by the `ng-model` attribute of the [`droptarget`](#droptarget) ui-sortable element.
+
+### index
+Type: [Integer](http://api.jquery.com/Types/#Integer)  
+Holds the original index of the item dragged.
+
+### model
+Type: [Object](http://api.jquery.com/Types/#Object)  
+Holds the JavaScript object that is used as the model of the dragged item, as specified by the ng-repeat of the [`source`](#source) ui-sortable element and the item's [`index`](#index).
+
+### moved
+Type: [Object](http://api.jquery.com/Types/#Object)/`undefined`  
+Holds the model of the dragged item only when a sorting happens between two connected ui-sortable elements.  
+In other words: `'moved' in ui.item.sortable` will return false only when a sorting is withing the same ui-sortable element ([`source`](#source) equals to the [`droptarget`](#droptarget)).
+
+### received
+Type: [Boolean](http://api.jquery.com/Types/#Boolean)  
+When sorting between two connected sortables, it will be set to true inside the `update` callback of the [`droptarget`](#droptarget).
+
+### source
+Type: [jQuery](http://api.jquery.com/Types/#jQuery)  
+Holds the ui-sortable element that the dragged item originated from.
+
+### sourceModel
+Type: [Array](http://api.jquery.com/Types/#Array)  
+Holds the array that is specified by the `ng-model` of the [`source`](#source) ui-sortable element.
+
+
+## Methods
+
+### cancel[()](http://api.jquery.com/Types/#Function)
+Returns: Nothing  
+Can be called inside the `update` callback, in order to prevent/revert a sorting.  
+Should be used instead of the [jquery-ui-sortable cancel()](http://api.jqueryui.com/sortable/#method-cancel) method.
+
+### isCanceled[()](http://api.jquery.com/Types/#Function)
+Returns: [Boolean](http://api.jquery.com/Types/#Boolean)  
+Returns whether the current sorting is marked as canceled, by an earlier call to [`ui.item.sortable.cancel()`](#cancel).
+
+### isCustomHelperUsed[()](http://api.jquery.com/Types/#Function)
+Returns: [Boolean](http://api.jquery.com/Types/#Boolean)  
+Returns whether the [`helper`](http://api.jqueryui.com/sortable/#option-helper) element used for the current sorting, is one of the original ui-sortable list elements.
+
+
+## Events
+
+### `ui-sortable:moved`
+Is emitted after the `stop` callback.
+In connected sortables it is also emitted after the `update` on the receiving sortable.
+
+```js
+$rootScope.$on('ui-sortable:moved', function (e, ui) {
+
+});
+```

+## Reporting Issues
+
+The following examples are provided as a good starting point to demonstrate issues, proposals and use cases.
+Feel free to edit any of them for your needs (don't forget to also update the libraries used to your version).
+
+* [Simple Demo](http://codepen.io/thgreasi/pen/jlkhr)
+* [Connected Lists](http://codepen.io/thgreasi/pen/uFile)
+
+Since some issues may be caused by jquery-ui-sortable and not by the wrapping that angular-ui-sortable does,
+please try your use case using [this plain jquery-ui sortable example](http://codepen.io/thgreasi/pen/rarQvR) before opening a new issue in the repositry.
