Display modes for multiple columns in SwiftUI

Hi,

On iPadOS, for three column layouts, is it possible to change the display mode in SwiftUI, like in the session "Build for iPad" (at 4'51)?

Also, is it possible to have 3 active columns on 9.7-inch iPad in landscape (with a narrower middle column so that the righthand column has enough room for content)?

Thanks
