Aha, undocumented requirements!  :-)

Well, i used a SimpleList, which ISA TreeView containing  
TreeViewColumns, but each section has its own TreeView and therefore  
there is no global header you can use to sort and such.  You could  
fake it with a button row at the top and some sizegroup magic, but it  
would probably not be worth it.

Yes, you can draw pretty much anything you want with a cellrenderer's  
RENDER method.  See the cellrenderer-popup example for inspiration;  
this uses Style methods to draw the cell to look just like a ComboBox  
in its OptionMenu replacement mode.

But, be warned; this means you'll be diving into the messy world of  
trying to figure out how themes interact.
