Hiding entire columns from the user interface

I need to hide a set of columns on a specific condition, for example, I want to hide 18 columns from the user after some nth column is filled.
The show_if expression may work, but it only hides the initial value of the column, when I want to hide the entire thing.
Thanks in advance for your help.

Indeed, Show_If should do what you want. I don’t know what you mean by “it only hides the initial value of the column, when I want to hide the entire thing.” Can yo explain?

Basically, the column input stays visible, while the initial value is hidden. So, what I wanted to ask was if I can hide the entire column with the column input AND the initial value.

Can you provide screenshots that demonstrate the unwanted behavior?

Sure. In a while.
