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;
    padding: 7px;
    position: relative;
    cursor: move;
}

Setting up the YUI Instance

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

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

Making the Node draggable with DD

Now that we have a YUI instance with the dd-drag and dd-scroll modules, we need to instantiate a DD instance from this Node.

var dd = new Y.DD.Drag({
    node: '#demo'
});

Making the Window Scroll

Now that we have a draggable Node, we need to plug the Plugin.DDWinScroll plugin onto the Drag instance.

var dd = new Y.DD.Drag({
    node: '#demo'
}).plug(Y.Plugin.DDWinScroll);
