Hello again, @mehdy!
I'm not sure, I think there may be no example in our examples explorer for version 7
but maybe there's one in v5 examples explorer
that you could fairly easily move into version 7.
In case this is a new concept you didn't try in v5 or know to be used back then, the advice I could give is, try to make a simple test case with the elements you require; once you get stuck, share here the test case highlighting what you're unable to achieve with the code, then we can give you some insight on how to make it happen. One way or another, there will be a way, I'm confident about it, just maybe not as intuitive as we'd like it to be.
So, if you can find an example in v5 you're having trouble to port to v7, or if you come with your scenario from the scratch and get stuck at some point, we'd be more than eager to help you move on. But without further leads, we are left wondering what you'd expect of the scenario you described.
Looking forward to your follow-up!
