Module security
From MoodleDocs
Location: Settings > Site administration > Security > Module security
- Certain activity modules may be disabled so that they do not appear in the "Add an activity" drop-down menu for teachers. The setting only applies to teachers - administrators are always able to add any activity to a course.
- The administrator can choose to restrict modules for all courses, requested courses or no courses.
- New courses can have the modules restricted by default if the admin checks the box Restrict modules by default
- The allowed modules are then selected from the box as in the screenshot below:
