Click affecting sibling class

Hi everyone, I have this content that opens on click
I would like to close the “current-open” content when I open another content In order to have max 1 open content.

Basically I need to do the 2nd click on the last element I clicked when I do the 1st Click on another one

I imagine that a lil script is required, but maybe is solvable just with animations? Have you ever faced this?

thanks for any help :slight_smile:
