I solved "partially using TreeDataGreed " and post a solution here
#How to select row on click on row in tree datagrid - #3 by scarfagna72

but i dont like it because I’ve to create a
TreeDataGreed need to create a JmixEntiy but id dont need to save it .

The best solution is to use a native Vaadin tree and Pojo or Dto.
I can do it from ViewController and code as I shown (look at the link) .

But could be nice to have a Jmix UI tool showing native Vaadin component to add to the View.
