Collapse when hidden checkbox missing

I have had my app for a while, since October last year. I used the old editor and it was great. However, now that I have started a new app, the new editor seems to be different. I cannot find the ‘collapse when hidden’ function when viewing the group properties.
Where have they moved it to? It’s quite frustrating because they removed it. I liked the old version better.

New version (the checkbox is missing)

Older version (on my older app) the checkbox is there

Hi there, @tarafield2015… you can find that checkbox on the Layout tab, assuming the parent container’s layout is not set to fixed.
