TL DR: How do I show additional fields of data and show it inside the rectangle (Read below for details.) Is there any way to add additional data like strings and ID numbers to show up on the tree using this widget? I have made it work like the demo project in my own app, however, I want it to show the names inside the rectangle instead of outside as shown here [look at child 1]:
I created a new (2.3.0) version of the widget. I tried to release it just now, but there seems to be a persistent bug in the Marketplace, blocking me from releasing this now. I have filed a support ticket at Mendix and hope they will fix it soon. If not DM me and I can share it already.
