Sometimes, courses get hidden instead of made unavailable to students. This results in the course disappearing from view in Blackboard. Only Instructors and teaching assistants have the option to hide courses from their course list in Blackboard. While students cannot hide courses, they can select a specific term from the drop down to filter their course listings.
When you hide a course, this only impacts your own view of the course list. It will NOT hide the course from your students. If you want to make the course available/unavailable to your students, you need to make it open/closed. See this knowledge base article to change course availability.

On your Courses page in Blackboard, click the ellipses next to a course and select "Hide Course."
