Layout dynamically resize

Hello,
I am new to this forum, so please excuse me if I make some mistakes.

I want to make a registration form that keeps more than one addresses and phones. Thus I created a vertical layout and inside this horizontal layouts with custom line edits and a custom button for delete. When I add a new address for example, I made the layout to expand using minimumSizeConstraint.

The problem is when I delete the an address the size of the layout remains the same, and I want it to colapse.

Does anyone have any idea? or another solution (maybe an other layout arrangement or to use other widgets)

I am happy to give more specification if I didn't made my problem clear.

Thank's in advance,
Gpetrous.

Nevermind my post. I solved it using fixed size constraint. But if you have an other implementation I would be more than gratefull.
