How to add menu tree in ViewMenuUI?

General
1

As per title, how do I create a menu tree based on the database value into MenuViewUI?

2

You could perhaps use the Tree component?

3

Is there any example which I can refer to ? Because I am new to vaadin, need some reference code to refer.

I have search the internet, none of the menu using menu tree, mostly use independent menu button to call the screen.

You could start with the
docs
 at least.
