>One example I can think of right off is Windows Explorer. It has a combo/treeview type control at the top called the Address Bar. Another great example is a drop down calendar control.

OK, so the Windows Explorer example is good ... I couldn't quite picture what you were getting at until you mentioned that.

So, I seem to remember reading something about this somewhere ... I tried searching here on the UT and wasn't coming up with anything. I must have read it elsewhere.

I'd guess you'd probably want to do something with the DrawItem event of the ComboBox to handle the actual drawing of the dropdown, but off the top of my head I can't remember exactly what I read about this. I'd have to do some more searching, maybe it was on the MSDN forums.
