'Declaration Public ReadOnly Property FieldGroups As ReadOnlyObservableCollection(Of FieldChooserGroup)
public ReadOnlyObservableCollection<FieldChooserGroup> FieldGroups {get;}
FieldGroups returns the collection of items that the field-group selector will display in its drop-down. By default the collection contains a single entry for each field-layout representing the fields of that field-layout. However if FieldFilters property is specified to subgroup fields, then a single field-layout can have multiple entries in this collection - one for the field-layout itself and one for each subgroup within that field-layout.
