the trick here is to use a wrapper that transitions the height (with overflow hidden). It can look at the real height of it's child
I adjusted your html structure a bit to make it happen

Thank you for your help, you helped me a lot. I'm new to Js, I don't know it very well, sometimes there are problems in implementing ideas
