Nestable

Just another fork of Nestable jQuery plugin developed by David Bushell then updated by Ramon Smit who deleted the repository later.

This covers the latest version. Some features may be added in the near future.

Try Nestable Demo

Installation

Via bower:

$ bower install --save nestable-fork

Via npm:

$ npm install --save nestable-fork

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}]}]

You can get a hierarchical nested set model like below.

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

The output will be like below.

[{"id":1,"parent_id":"","depth":0,"lft":1,"rgt":2},{"id":2,"parent_id":"","depth":0,"lft":3,"rgt":4},{"id":3,"parent_id":"","depth":0,"lft":5,"rgt":10},{"id":4,"parent_id":3,"depth":1,"lft":6,"rgt":7},{"id":5,"parent_id":3,"depth":1,"lft":8,"rgt":9}]

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)
• callback callback function when an element has been changed (default null)

These advanced config options are also available:

• contentCallback The callback for customizing content (default function(item) {return item.content || '' ? item.content : item.id;})
• 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')
• noDragClass The class applied to an element to prevent dragging (default 'dd-nodrag')
• 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')
• noChildrenClass The class applied to items that cannot have children (default 'dd-nochildren')
• 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>')
• includeContent Enable or disable the content in output (default false)
• listRenderer The callback for customizing final list output (default function(children, options) { ... } - see defaults in code)
• itemRenderer The callback for customizing final item output (default function(item_attrs, content, children, options) { ... } - see defaults in code)
• json JSON string used to dynamically generate a Nestable list. This is the same format as the serialize() output
