Try Nestable Demo

Write your nested HTML lists like so:

<div class="dd">
    <ol class="dd-list">
        <li class="dd-item" data-id="1">
            <div class="dd-handle">Item 1</div>
        </li>
        <li class="dd-item" data-id="2">
            <div class="dd-handle">Item 2</div>
        </li>
        <li class="dd-item" data-id="3">
            <div class="dd-handle">Item 3</div>
            <ol class="dd-list">
                <li class="dd-item" data-id="4">
                    <div class="dd-handle">Item 4</div>
                </li>
                <li class="dd-item" data-id="5">
                    <div class="dd-handle">Item 5</div>
                </li>
            </ol>
        </li>
    </ol>
</div>

Then activate with jQuery like so:

$('.dd').nestable({ /* config options */ });

The change event is fired when items are reordered.

$('.dd').on('change', function() {
    /* on change event */
});

You can get a serialised object with all data-* attributes for each item.

$('.dd').nestable('serialize');

The serialised JSON for the example above would be:

[{"id":1},{"id":2},{"id":3,"children":[{"id":4},{"id":5}]}]

You can change the follow options:

• maxDepth number of levels an item can be nested (default 5)
• group group ID to allow dragging between lists (default 0)

These advanced config options are also available:

• listNodeName The HTML element to create for lists (default 'ol')
• itemNodeName The HTML element to create for list items (default 'li')
• rootClass The class of the root element .nestable() was used on (default 'dd')
• listClass The class of all list elements (default 'dd-list')
• itemClass The class of all list item elements (default 'dd-item')
• dragClass The class applied to the list element that is being dragged (default 'dd-dragel')
• handleClass The class of the content element inside each list item (default 'dd-handle')
• collapsedClass The class applied to lists that have been collapsed (default 'dd-collapsed')
• placeClass The class of the placeholder element (default 'dd-placeholder')
• emptyClass The class used for empty list placeholder elements (default 'dd-empty')
• expandBtnHTML The HTML text used to generate a list item expand button (default '<button data-action="expand">Expand></button>')
• collapseBtnHTML The HTML text used to generate a list item collapse button (default '<button data-action="collapse">Collapse</button>')

Inspect the Nestable Demo for guidance.
