Extending the navigation Optimizely CMS 11.21 and higher

You can extend the navigation to let editors access Optimizely CMS and other products from the global menu.

• The [MenuItem] attribute adds an interface to the menu, see Adding and configuring menu items.
• You can also configure and implement a custom menu provider, see Using menu providers.

Attributes and menu providers must reside in an assembly configured as [a shell module](doc:configuring-shell-modules].

In version 11.21 of Optimizely CMS UI, a new global navigation menu was introduced that differs slightly from how it worked before. If you are upgrading from the old global navigation menu to the new, see Upgrading navigation.
