Creates a new group and adds it to the current group.
NuGet Package: DevExpress.Win.Navigation
The newly added group.
This method does nothing in the LayoutGroup class. It is overridden in the LayoutControlGroup class to create a new LayoutControlGroup object.
The default layout type is determined by the LayoutGroup.DefaultLayoutType property. By default, it is set to LayoutType.Vertical, so the new group is positioned at the bottom of the current group. If this property is set to LayoutType.Horizontal, the new group is positioned at the current group’s right edge.
To add layout items to the new group, use the LayoutGroup.AddItem and BaseLayoutItem.Move methods.
