'Declaration Public Property AllowNestedTabGroups As Infragistics.Win.DefaultableBoolean
public Infragistics.Win.DefaultableBoolean AllowNestedTabGroups {get; set;}
By default, AllowNestedTabGroups resolves to false. When this property resolves to true, the end user may drag tabs (depending upon their AllowDrag) to create nested tab groups. A nested tab group is an MdiTabGroup that contains MdiTabGroups instead of directly containing MdiTab instances. Nested tab groups allow for more control over the layout of the tabs.
