Hi Katja,
I have found the (well-hidden) course (not site) -wide setting which enables you to completely hide the name of hidden courses to (unenrolled) students, not just display them in grey.
- Log in as a teacher (or admin) in one of your courses
- go to Administration
- set Availability to: This course is not available to students
- in Hidden sections:
- setting Hidden sections are shown in collapsed form will display your course name greyed out
- setting Hidden sections are completely invisible will completely hide any course name that is set to This course is not available to students.
- setting Hidden sections are shown in collapsed form will display your course name greyed out
Course hidden sections
This option allows you to decide how the hidden sections in your course are displayed to students.
By default, a small area is shown (in collapsed form, usually gray) to indicate where the hidden section is, though they still can not actually see the hidden activities and texts. This is particularly useful in the Weekly format, so that non-class weeks are clear.
If you choose, these can be completely hidden, so that students don't even know sections of the course are hidden
Please note that if a course is a) made unavailable to students and b) Hidden sections are completely invisible its name will not be displayed to students not enrolled in this course, but it will still appear greyed-out to those students who have been enrolled in the course.Hope that helps!
Joseph
