Hi! Is it possible to made an Treeview or something like this in
the Option Page or somewhere else?

I had tried too, like the including of an Editbox, but it didn't worked
<TreeView Name="Name" X="11" Y="100" Width="-100" Height="100"/>

Best regards
SH

The theme seems to support Treeview but I have never done anything with and there doesn't seem to be any code to support it.
