Drag and drop menu

Hi! I hope someone can help me with this. I am trying to create a menu like this:

I am populating the boxes via an xml file. I have just about everything working except for the scrollbar.

I have the scrolltrack portion working (if i click on the track it advances my clip in the opposite direction of the scroll motion) but I can’t seem to get the drag functionality working. It would be great if I could just reuse the scrollpane component but I can’t drag and drop my clips out of the scrollpane window. Any ideas? I’d also be happy to hear from anyone on how they would go about creating a menu like the one above. I’ll post what I’ve got done so far later. Thanks!
