✅ WPF trees with some items that can't be selected
I'm building a UI with a tree view where some items exist only to group children. The tree will function as a kind of vertical tree control. When most items in the tree are selected, I'll show a control next to the tree. But the items that are only groups don't have a control to show. So I don't want to allow their selection.
How do I pull that off?
