Setting up the Delegate container and items

First we need to create an HTML Node to act as the delegate container and give it some nodes to make draggable.

<div id="play">

    <div id="demo">
        <ul>
            <li>Item #1</li>
            <li>Item #2</li>
            <li>Item #3</li>
            <li>Item #4</li>
            <li>Item #5</li>
            <li>Item #6</li>
            <li>Item #7</li>
            <li>Item #8</li>
            <li>Item #9</li>
            <li>Item #10</li>
        </ul>
    </div>
    
    <div id="drop">Drop on me</div>
</div>

Now we give them some CSS to make them visible.

#demo {
    width: 200px;
}
#demo ul li {
    border: 1px solid black;
    background-color: #8DD5E7;
    cursor: move;
    margin: 3px;
    list-style-type: none;
    z-index: 2;
    zoom: 1;
}
#play {
    position: relative;
    zoom: 1;
}
#drop {
    border: 1px solid black;
    background-color: #eee;
    height: 50px;
    width: 200px;
    position: absolute;
    bottom: 5px;
    right: 5px;
    zoom: 1;
}
#drop strong {
    font-weight: bold;
}
#drop.yui3-dd-drop-over {
    background-color: #ccc;
}

Setting up the YUI Instance

Now we need to create our YUI instance and tell it to load the dd-delegate module.

YUI().use('dd-delegate', 'dd-drop-plugin');

Making the Nodes draggable

Now that we have a YUI instance with the dd-delegate module, we need to instantiate the Delegate instance on this container and nodes.

YUI().use('dd-delegate', 'dd-drop-plugin', function(Y) {
    var del = new Y.DD.Delegate({
        container: '#demo',
        nodes: 'li'
    });
});

Listening to some events

The Delegate object is a bubble target for the DD.Drag instances. So you can listen on it for all drag related events.

YUI().use('dd-delegate', 'dd-drop-plugin', function(Y) {
    var del = new Y.DD.Delegate({
        container: '#demo',
        nodes: 'li'
    });

    del.on('drag:end', function(e) {
        del.get('currentNode').setStyles({
            top: 0,
            left: 0
        });
    });

});

Adding a Drop Target

Now we can add a normal Drop Target to the page.

var drop = Y.one('#drop').plug(Y.Plugin.Drop);

Once that is created, we can add a drop:hit listener and manipulate the drag instance as we normally would.

var drop = Y.one('#drop').plug(Y.Plugin.Drop);
drop.drop.on('drop:hit', function(e) {
    drop.set('innerHTML', 'You dropped: <strong>' + e.drag.get('node').get('innerHTML') + '</strong>');
});

YUI().use('dd-delegate', 'dd-drop-plugin', function(Y) {
    var del = new Y.DD.Delegate({
        container: '#demo',
        nodes: 'li'
    });

    del.on('drag:end', function(e) {
        del.get('currentNode').setStyles({
            top: 0,
            left: 0
        });
    });

    var drop = Y.one('#drop').plug(Y.Plugin.Drop);
    drop.drop.on('drop:hit', function(e) {
        drop.set('innerHTML', 'You dropped: <strong>' + e.drag.get('node').get('innerHTML') + '</strong>');
    });
    
});
