Show-if column

[Dexpertio_LTDA]

I would like to show a new question on a form based on the previous answer. That is, if the person answered the previous question and wants to complement his answer, another complementary question is shown. How do I do that? With show-if in the column? But what if I want this to be an action, that is, the person asks for this complementation?

Actions cannot be used in form views, so you can only base the Show? decision on the values of other columns.

But then I can use something like: if the last column is not empty: [This_] is not empty?
