I need to pop-up a menu when the user-right clicks on a graphic, where the contents of that menu are dictated by where the mouse is currently hovering over an image. So it's not as easy as showing a DIV...the actual contents of the menu need to be built by the client-side code. I have all the data I need in scope, I just don't know how to build a menu on-the-fly like this.

Any ideas about a good approach to accomplish this?

Thanks!
Walter
