Has anyone written a cascading popup-style uicontrol?

e.g., similar to what is possible w/ uicontext menus, only as a uicontrol so it can "live" in a figure or panel? (As near as I can tell, given present Matlab GUI object options, one would have to implement this, descending level by level, in the callbacks of popup-style uicontrols--I'm just wondering if anyone has already done this in a general way so that all one has to do is specify the lists to display at the various levels and the rest is done for you.) Thanks!

The UIContextMenu property (of most graphic objects) allows you to associate a right-click activated uicontextmenu object with the graphics object.

Yes, I'm well aware of that--I use it in another app--but that's not what I want: I don't want the user to have to right-click on anything, I want a "regular" popup uicontrol, but when you hover over or select one of its choices, another popup opens up with another list of sub-choices, etc. Basically, I want to be able to nest popup uicontrols within one another. (Note: I've already submitted an "enhancement request" for this; I'm just wondering/hoping someone has already implemented it using extant resources.)

That sounds a bit familiar; I think someone else asked for much the same thing about a year-ish ago.
