. And another question, if someone knows.
How to make such an interaction so that when you click on an element, a hidden group of elements appears?

Answer 1

1. The header must be a component.
All interactive in the master component is transferred to all the others.
2. Hidden elements must be a separate frame outside of the frame on which it should appear.
