Separator
A Separator is a control without a Header or Content properties. It cannot accept any child controls. It resembles a horizontal or vertical line (depending on the items control it is placed into), and is used as a simple divider to split or separate items within an items collection into groups.
Separators are commonly used with items controls such as menus/menu items, toolbars, and status bars. Separators are not selectable objects.
