Folder Structure of the Tree

[developeryoda]

Hello everybody, first of all a happy new year to all! To my question, correct me if I'm wrong, currently we can only create a tree view from one data type. This means only from one value type. Like we have a value of type A:

• A
• A
• A

Is it possible or how can I best solve this that I can display a folder view. e.g.

• A
  • Test1
  • Test2
  • A1
    -Test3
• B
• C

Something like that? Thank you very much it is a very nice development! and I would be very happy about the soon help!
