Steps to reproduce the issue

Currently if your using a repeatable formfield there is an entire fieldset that is hidden unless the
formfield meets its condition. So its easily possible to turn and repeatable completely on/off based on user inputs.

Expected result

It would be useful if there was a "conditional" formfield where much like the repeatable your able to hide an entire fieldset. This could also have a "modal" param much like showon where if it was active would display this sub-fieldset in a modal and where if not would just display it like normal.

Actual result

Currently not possible

System information (as much as possible)

Additional comments

This would be useful where there is a large group of parameters that don't make sense to display unless some other condition has been met.
