You might consider using a javascript library such as JQuery to help you with this sort of thing--a lot of these sorts of functions are built-in.

Kevin is right do not try to implement a dragable feature on your own. Jquery and Jquery UI have already done this.

Learn JQuery! You'll never regret it.

Look here for a demo of draggable object using JQuery library : link text

Good luck!
