Layouts tend to resize vertically better than they do horizontally. Modern websites address this issue in various ways, commonly by having elements of the page only appear at certain break points. For example this website, "SteamSpy" (it's a site that tracks sales on the largest pc gaming platform "Steam"), only displays the element on the right with a sufficiently large window:
I would like to do something similar. I would like to show a master-detail portal on the right of a layout when the window is sufficiently wide.
I could do that with two different versions of the same layout + script triggers and such, but I would very much like to avoid doubling the number of form layouts I have to maintain. Any ideas on how to achieve this in a single form layout?
