Setting up the Node

First we need to create an HTML Node to make draggable.

<div id="demo">Drag Me</div>

Now we give that Node some CSS to make it visible.

#demo {
    height: 100px;
    width: 100px;
    border: 1px solid black;
    background-color: #8DD5E7;
    cursor: move;
}

Setting up the YUI Instance

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

YUI().use('dd-drag');

Making the Node draggable

Now that we have a YUI instance with the dd-drag module, we need to instantiate the Drag instance on this Node.

YUI().use('dd-drag', function(Y) {
    //Selector of the node to make draggable
    var dd = new Y.DD.Drag({
        node: '#demo'
    });   
});
