The instructor dashboard has a top menu similar to the primary menu displayed on the front-end of the website.
But there are times when you may wish to display a different top menu for the instructors on the instructor dashboard menu than the normal one.
You can get this done using the Instructor Dashboard Menu setting under the Appearances ➞ Menus section as shown below.
Create a new menu for Instructors or use an existing one and then check the Instructor Dashboard Menu in the Menu Settings below.
Note: This setting requires that you have the Visibility setting enabled for Instructors under Appearances ➞ Admin Customizer ➞ Visibility
