Drag Me

### Setting up the Node

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

    <div id="demo"><h2>x</h2>Drag Me</div>

    <div id="demo"><h2>x</h2>Drag Me</div>

<div id="demo"><h2>x</h2>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;}#demo h2 {    padding: 0;    margin: 0;    position: absolute;    top: 5px;    right: 5px;    font-size: 110%;    color: black;    font-weight: bold;    cursor: move;}

    #demo {
        height: 100px;
        width: 100px;
        border: 1px solid black;
        background-color: #8DD5E7;
        padding: 7px;
    }
    #demo h2 {
        padding: 0;
        margin: 0;
        position: absolute;
        top: 5px;
        right: 5px;
        font-size: 110%;
        color: black;
        font-weight: bold;
        cursor: move;
    }

#demo { height: 100px; width: 100px; border: 1px solid black; background-color: #8DD5E7; padding: 7px; } #demo h2 { padding: 0; margin: 0; position: absolute; top: 5px; right: 5px; font-size: 110%; color: black; font-weight: bold; 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');

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

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'}).addHandle('h2');

    var dd = new Y.DD.Drag({
        node: '#demo'
    }).addHandle('h2');

var dd = new Y.DD.Drag({ node: '#demo' }).addHandle('h2');

### 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'}).addHandle('h2').plug(Y.Plugin.DDWinScroll);

    var dd = new Y.DD.Drag({
        node: '#demo'
    }).addHandle('h2').plug(Y.Plugin.DDWinScroll);

var dd = new Y.DD.Drag({ node: '#demo' }).addHandle('h2').plug(Y.Plugin.DDWinScroll);
