Is it possible to expand/contract categories?
Sorry, that is currently unfortunately not possible.
Would you please be kind enough to add it to the wishlist along with the ability to have more than one column?
If you want multiple columns, you might consider using TTMSFNCTreeView
Thanks for the suggestion. I did look at that but there are a variable
number of columns per group. I think I am going to use a tableview and a
custom drawn responsive list once I figure out how do do it!
