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)
