# accessibilityElement A Boolean value that determines whether the accessibility element participates in the accessibility hierarchy. ``` @property (getter=isAccessibilityElement) BOOL accessibilityElement; ``` ## Discussion Use this property to expose this object to accessibility clients as a functional interface element. For example, when you place a button in a window, the system typically creates a button cell inside a button control inside a container view inside a window. Users, however, don’t care about the view hierarchy details. They should only be told that there’s a button in a window. If this property is set to , accessibility clients ignore this element. By default, `NSView` and its subclasses set this value to ; however, if your `NSView` subclass adopts one of the accessibility protocols, the system changes the default value to . ## See Also [`NSAccessibilityUnignoredDescendant`](/documentation/AppKit/NSAccessibility-swift.struct/unignoredDescendant(of:)) Returns an unignored accessibility object, descending the hierarchy, if necessary.
