How would one create a collapsable FAQ module?

I would love to create a collapsable FAQ accordeon.

What I’ve tried
I’ve created 2 variants (open and closed question). Then I combined an instance of that interactive component into another component with smart layout, combining multiple instances into a list.

The result + problem
It folds open successfully but the second / other questions / rest of the page sections don’t move down to make space for it.

Bonus question
As a bonus question I’d like to make it so that only 1 question is in the open state at the same time.
