FSelectGroup<T> class
A set of items that are treated as a single selection.
Typically used to group multiple FSelectGroupItem.checkboxs or FSelectGroupItem.radios.
For touch devices, a FSelectTileGroup is generally recommended over this.
See:
- https://forui.dev/docs/form/select-group for working examples.
- FSelectGroupStyle for customizing a select group's appearance.
