In this course format:
- sections can be added inside other sections
- each section (regardless of its nesting level) can be shown either on the same page as parent or on a separate page. Teacher can change it in edit mode.
- If section is displayed on a separate page, it's name is displayed as a link and on this page the link "Back to ... " is displayed
- If teacher hides a section all nested sections and activities become hidden as well.
Please note that if section has both activities and subsections activities are displayed first.
