Form definition with 2 dependable select components

Camunda 7 Topics
1

Hi,
we are using camunda 7 and I would like to know, how can we create a form that contains 2 select components, which are dependable to each other, i.e for example:
I have select component 1 and select component 2. Default value by both is .
Then, I would like, when I choose the first one (when the first one got a value) the second select component to be disabled or hide. (pic in attachment for more explanation). The Key from first select component is “Var”. That means when Var != null is, the second component should hide or be disabled.

I have tried with “Hide if fx” but it doesn’t work :frowning:
