Servoy 8.0.0 beta 1

I’m having a difficult time getting any sort of responsive form creation to work.

If I try and make a 12grid I can get about as far as putting the Container on the form (sometimes), but I don’t think I ever successfully get a row on the page (I see an outline for it at first, but then it goes away if I try and place a column in it)

Are there any sample solutions or documentation I’m missing?
