Hide an EntityBoxLong

Good afternoon,


We want to hide a BoxLong that is into an entity.

As you can see in the image, I'm in Company entity. We have a field, "Persona", that is an advanced search selection field. We want that, if this field has a person inside, then ALL the PersonBoxLong that is in the screen hides and the fields into it get non mandatory.

How can I do to make it?


Thanks in advance.
