Could someone please tell me if it's possible to do what I'm trying to do? I just can't figure it out.
What I want to do is to create a menu which is "split" on the right hand side. This picture will show exactly what I mean.
(This is a menu from a real program)

You see how it's "split" on the right hand side? allowing two different areas to be highlighted.
I am able to get the menu to "look" the same by adding in a background image, however, it does not fit my needs because I need to be able to click on both the actual menu and the little black boxes. Here's a picture of what my menus look like.

If anyone at all has any idea on how I could acheive this I would be most grateful!
Thanks!
