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>'`)
|
||||
* `dropCallback` The callback method which is called when an item has been successfully moved. It has 1 argument: object with all details (default `null`)
|
||||
|
||||
`dropCallback` details object:
|
||||
|
||||
* `sourceId` - id of moved element
|
||||
* `destId` - id of destination parent or null if element was moved directly as root
|
||||
* `sourceEl` - whole moved element if you want to gather additional info about it
|
||||
* `destParent` - whole destination parent element (if root, then it returns direct container)
|
||||
* `destRoot` - contains destination group where element was dropped
|
||||
* `sourceRoot` - contains source group where element belonged to before user started dragging it
|
||||
