# altersStateOfSelectedItem

When the value of this property is `YES`, the selected menu item’s `state` is set to `NSControlStateValueOn`. When the value of this property is `NO`, the menu item’s `state` is not changed. When this property changes, the `state` of the currently selected item is updated appropriately. This property is ignored for pull-down buttons.

```
var altersStateOfSelectedItem: Bool { get set }
```
