Hierarchical Data

Hi guys, I’m having difficulty of understanding Hierarchical Data implementation of Vaadin 8. But It just seems easy in Vaadin 7.

for examlple I want to implement a TreeGrid with this hierarchy,

  • Branch

    • Division

      • Colleges

        • Offices

          • Departments

How to should I implement this?

(This is my implementation of TreeGrid from Vaadin 7)


nevermind guys… I have figure it out. :smiley:
