Basic Drag and Drop

The YUI Drag and Drop Utility lets you make HTML elements draggable.

For this example, we will enable drag and drop for the three <div> elements.

Create the demo elements:

Next, we define a custom drag and drop implementation that extends YAHOO.util.DD. Drag and drop exposes many interesting moments that you can use to implement custom functionality. In this example, we override the startDrag and endDrag moments to adjust the z-index property so that the dragged element is always on top.

Now we create the instances of YAHOO.example.DDOnTop, passing the element ids or references for our demo elements.
