In order to deactivate or delete a content unit, log in as an administrator or instructor and access the dashboard of the course you want.

Next, to the units, you will notice the Edit button with a little arrow next to it (1). Clicking on it, two options (2) will be revealed:

• Toggle status: Clicking on it, it will deactivate the unit. If the unit is already inactive, this option will reactivate it. The unit status is automatically reflected on the learner's page.
• Delete: Clicking on it, the unit will be deleted and removed from the course.
