The course menu appears on the left side of a course and contains links to materials and tools within the Blackboard site. Course menu structure may vary significantly between courses because your instructor can customize the style and the content.
You can expand or collapse the course menu frame by moving your pointer near the border and clicking the arrow. The view of your menu (collapsed or expanded) sticks. In other words, when you log out and log back in, the expanded or collapsed state of your course menus will remain in the most recent status.
