A new Site Designer option lets you hide navigation items from authenticated users, so that you can create links that guests alone will see. You can use this option, for example, to add a Create Account link that appears only to unauthenticated users: after logging in, users will no longer see a link prompting them to create an account. To apply this guest-only behavior to a navigation item, open its Options section and enable This navigation item only displays for unauthenticated users.
