How do I manage Course Navigation links?
As an instructor, you can control which links appear in Course Navigation. Canvas includes a set of default Course Navigation links that are shown by default and cannot be renamed. Depending on your course configuration, other links may be available and may be customizable.
Links to sections that don't have any content and that students cannot create content for are automatically hidden for students and display the Visibility icon to instructors. For example, if there are no learning outcomes set for the course, you see the Outcomes link with the Visibility icon, but students cannot see the link at all. Configured External Apps may create additional Course Navigation links.
Disabling a course navigation link creates the following redirects:
Reordering and hiding Course Navigation links for Announcements, Assignments, Discussions, and Files also affects the course tabs in the Dashboard course view for all users. Additionally, disabling the Files link hides the Files tab in the Content Selector in the Rich Content Editor for students.
The following course navigation links will still be visible to instructors even if they have been hidden or disabled: Home, Announcements, Assignments, Collaborations, Conferences, Discussions, Files, Grades, Modules, Outcomes, Pages, People, Quizzes, Rubrics, Settings, and Syllabus.
