Collapsible panel

Hello!

I am trying to make a panel that is collapsible. So far it is going alright, but I am looking for some guidance towards getting it to work completely. My problem is that the content of the panel is collapsing, but the panel itself isn't.

Do I need to add event bindings or something for the panel to collapse both it's content and size, or can you do it through properties?

Looking for some guidance here, any answers appriciated.

Regards

Christian
