# ContextMenu **Also known as:** RightClickMenu, PopupMenu, ShortcutMenu ## Description BitContextMenu opens a menu over an area of the page rather than from a button: where the area is right-clicked, or from the keyboard with Shift+F10 or the Menu key while the focus is in it. The menu is a BitMenuButton's, with its items, keyboard, submenus and check and radio items. ## Parameters | Name | Type | Default Value | Description | | :--- | :--- | :------------ | :---------- | | ChildContent | `RenderFragment?` | null | The content of the area the menu is opened over. | | CloseOnItemClick | `bool` | true | Whether the menu closes once one of its items is clicked. | | IsOpen | `bool` | false | Whether the menu is open.
