The scrolling behavior of the layout's sections in relation to the main layout axis.
- iOS 13.0+
- Mac Catalyst 13.0+
- tvOS 13.0+
By default, each section lays out its content along the main axis of its layout, defined by the layout configuration's
scroll property. You can change this behavior for a particular section by setting its
orthogonal property to a different value than its default UICollectionLayoutSectionOrthogonalScrollingBehaviorNone. Setting any other value for this property makes the section lay out its content orthogonally to the main layout axis.
