Drag & Drop: Window Scrolling

Using the Window Scroll DD Plugin


Drag Me

Setting up the Node

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

  1. <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.

  1. #demo {
  2. height: 100px;
  3. width: 100px;
  4. border: 1px solid black;
  5. background-color: #8DD5E7;
  6. padding: 7px;
  7. }
  8. #demo h2 {
  9. padding: 0;
  10. margin: 0;
  11. position: absolute;
  12. top: 5px;
  13. right: 5px;
  14. font-size: 110%;
  15. color: black;
  16. font-weight: bold;
  17. cursor: move;
  18. }
#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.

  1. 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.

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

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