Angular UI NestedSortable

An Angularjs ui component that can sort nested lists.

Features

• Items can be sorted in their own list, moved across the tree, or nested under other items.
• It is possible to define elements that will not accept a new item/list
• Data binding. If you change the order, the data you bound will be updated.

Usage

Angularjs script

var app = angular.module('nestedSortableDemoApp', [
	'ui.nestedSortable'
]);

Injecting ui.nestedSortable to your App.

HTML View or Templates

<ol ui-nested-sortable="" ng-model="list">
  <li ng-repeat="item in list" ui-nested-sortable-item="">
    <div ui-nested-sortable-handle>
      {{item.title}}
    </div>
    <ol ui-nested-sortable="" ng-model="item.items">
      <li ng-repeat="subItem in item.items" ui-nested-sortable-item="">
        <div ui-nested-sortable-handle>
          {{subItem.title}}
        </div>
      </li>
    </ol>
  </li>      
</ol> 

• Adding ui-nested-sortable to your root element.
• Using ng-model to bind the list data with element. It should be an array.
• Adding ui-nested-sortable-item to your item element, it always follow the ng-repeat attribute.
• Adding ui-nested-sortable-handle to mark which element do you want to handle the drage action
• All ui-nested-sortable, ng-model, ui-nested-sortable-item and ui-nested-sortable-handle are necessary. And they can be nested.
• If you add a nodrag attribute to an element, the element won't response for the drag action.
