Sort Header Row

[nesken]

Hi guys, can anyone help me?
I am following this examlpe:
https://www.primefaces.org/showcase/ui/ ... roup.xhtml

I have a question:
How could i use "sortBy" only in rows of the Audi's group?
Remembering that the Brands are already sorted.
Thanks in advance!

No, you can't sort only in one group. If you want that, pre-sort them in your model.
