Nestable
========
### Drag & drop hierarchical list with mouse and touch compatibility (jQuery / Zepto plugin)
[**Try Nestable Demo**](http://dbushell.github.com/Nestable/)
## Usage
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 */ });
### Events
The `change` event is fired when items are reordered.
$('.dd').on('change', function() {
/* on change event */
});
### Methods
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}]}]
### Configuration
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>'`)
