Appearance of design editor

I want to use the function “Collapse this element’s height when hidden”, however check box doesn’t appear on my design editor property. My app was built by other guy who might have made it invalid. Does anybody know how to revive it?

Assuming you’re using the new responsive engine, the ‘collapse when hidden’ checkbox can be found on the ‘layout’ tab for the element, but only if the element’s parent container has a responsive layout type (i.e. not ‘fixed’).

Thanks you so much. I think I found it although it was technically complex to resize it with unfixed parent group. Thanks anyway!
