[base] Hide elements under certain conditions

I am using base to create a form. On this form there are multiple subforms.
However one of these subforms isn’t required under most conditions.

So, if the TypeId equals 3 then show this subform and all its elements (labels, formatted fields), if TypeId does not equal 3 then I want to hide it as that information doesn’t need to be submitted to the database and it my confuse users.

If I can’t get it to change when 3 is entered, could I use a push button instead that users click when required?

Is that possible at all? Im on a mac if that makes a difference (i doubt it does)

Hide/reveal of Controls based upon a condition which can be done through macros. Please see this post: click here.

There is a sample (link) in the first comment.

You cannot hide a subform in one action. You need to hide all the elements on the subform individually.
