BarHeaderItem is a bar item that can be added to a PopupMenu or BarSubItem (sub-menu) to give a caption to a set of items that follow this BarHeaderItem.

PopupMenu.MultiColumn and
BarLinkContainerItem.MultiColumn inherited property, respectively.

MultiColumn property of the item's owner menu.
It is possible to customize multi-column mode settings in a centralized way, using these properties:
