Can't find 'collapse this elements height when hidden' checkbox

Hey Guys,

Could someone tell me where I can find the checkbox that says:

‘collapse this elements height when hidden’

According to Bubble it should be in the layout section, but I’m having no luck.

Any help would go a long way - losing my mind over this!

Thank you:)

note: it’s no longer called ‘collapse this element’s height when hidden’, as in the new Responsive Engine both height and width can be collapsed when hidden, depending on the parent container layout type
