Hiding groups

[Nat]

Is there a way to hide some groups of items ?

You can collapse them with the disclosure triangles, but I don't think you can hide them completely.
Curiosity: why do you want this?

I have different projects grouped on the same file but i don't want to print all of them (for example).
So i was looking for the hide option...
