Listview - getting started in BP

This is a really great write-up, and even though I had 0 knowledge going into this, I think I’ve been able to follow along, though with some difficulty.

My question concerns the TreeView. I’m able to get all actors of class and their children, but I’m also trying to get the children’s children as well.
For example, if I have:
VBox
->Box1
->->Box2
->Box3
Only Box1 and Box3 appear in the tree view, and Box1 doesn’t display that it has any children (unless I Include All Descendents, but the hierarchy remains broken). I was wondering how to implement this, if at all. I assume the way to do so is in the initial Event Construct, but I only found 2 examples with the node networks using it and didn’t know if I was missing anything, such as iterating through children, perhaps the Get Item Children func?

Thanks!
