[Closed] maxscript rollout in maxform

is there the equivalent of a subrollout or something that allows collapsing a group of labels, buttons, checkboxes

I’ve looked at groupbox, container and panel classes in system.windows.forms namespace.
They don’t seem suitable. I could simulate the look of a collapsable groupbox but it would mean that I would have to ask maxscript to shuffle GUI elements up and down which would likely be very slow.
