Question

I have tried for some time to work out a way of sorting nested categories with jQuery. I failed to build my own plugin to do this, so I tried to find something that were available already. Tried a few hours now with this one, http://www.jordivila.net/code/js/jquery/ui-widgetTreeList_inheritance/widgetTreeListSample.aspx and cant get it to work.

What are the alternatives of creating a jQuery / jQuery UI script that handles sorting children and parent categories in a way that can be combined with a AJAX PHP backend to handle the actual sorting in the database?

Thanks!

I used the widget from http://www.jordivila.net/jquery-widget-inheritance.html to sort nested categories and it worked for me.

Try using this simple html file

<script src="http://www.jordivila.net/code/js/jquery/ui-widgetTreeList/widgetTreeList.js" type="text/javascript"></script>
<script src="http://www.jordivila.net/code/js/jquery/ui-widgetTreeList_inheritance/widgetTreeList_Sort.js" type="text/javascript"></script>

<link href="http://www.jordivila.net/code/js/jquery/ui-widgetTreeList/widgetTreeList.css" rel="stylesheet" type="text/css" />

<style type="text/css">
    #treeListSortable {width:300px;}
</style>

    <script type="text/javascript">
        $(document).ready(function() {
        $('#treeListSortable').treeListSortable();
        });

    </script>

                <ul id="treeListSortable">
                      <li>Node 1
                        <ul>
                            <li>Node 12</li>
                            <li>Node 9</li>
                            <li>Node 7
                                <ul>
                                    <li>Node 6</li>
                                    <li>Node 11</li>
                                    <li>Node 10</li>
                                    <li class="ui-treeList-open">Node 8
                                    <ul>
                                        <li>Node 5</li>
                                        <li>Node 2</li>
                                        <li>Node 4</li>
                                        <li>Node 3</li>
                                    </ul>
                                    </li>
                                </ul>
                            </li>
                            <li>Node 13</li>
                        </ul>
                      </li>
                </ul>
