The navigation menu in your header is automatically duplicated across all your pages as it is, so any change to it updates every page at once. If you need a different navigation menu for one of your pages, convert it to a local element.
- Go to the page you want to create a local navigation menu for.
- Click the navigation menu in the header to activate Navigation settings.
- Click the More icon, then Convert to local element.
Any changes you now make to the navigation menu on this page only apply to this page.
To undo, click Undo in the top bar, or click the More icon again and choose Revert to global element.
