The Windows Forms component displays a menu at run time. All submenus of the main menu and individual items are objects. ## Key Properties A menu item can be designated as the default item by setting the property to `true`. The default item appears in bold text when the menu is clicked. The menu item's property is either `true` or `false`, and indicates whether the menu item is selected. The menu item's property customizes the appearance of the selected item: if is set to `true`, a radio button appears next to the item; if is set to `false`, a check mark appears next to the item. ## See also - - - - - - [MenuStrip Control Overview](menustrip-control-overview-windows-forms.md)
