Class MenuItemCollection

Namespace

SharpConsoleUI.Controls

Assembly

SharpConsoleUI.dll

Observable collection of MenuItems used for both MenuItem.Children and MenuControl.Items. Overrides ClearItems so Clear() fires actionable Remove events per item — the base ObservableCollection only fires a single Reset with no OldItems, which would prevent MenuControl from detaching items and disposing their bindings.
