I want to use Plasma::BoxLayout in my applet to show a collection of items, and when clicking on one of them I want to hide the other items and show a different item with information relative to the selected item, but it doesn't remove the items from the layout as I would expect. Maybe I didn't explain it correctly but...

As code is much better than words I've created a little test case that show the bad behavior.
I will attach it to this bug.
