A CourseSection is a structural grouping that organises lessons within a Course. Sections represent milestones or learning stages — each section should bring the member one step closer to the course’s overall learning goal. Sections are ordered by DisplayOrder and can be set to unlock immediately or after a delay, using the same UnlockType / UnlockAfterDays mechanism as individual lessons:
UnlockTypeMeaning
ImmediateSection is available as soon as the member enrols
SequentialUnlocked only after the previous section is completed
TimedUnlocked after the number of days specified by UnlockAfterDays
Sections are optional — lessons can belong directly to a course without a section. However, using sections can help create a clearer learning path for members, and allows you to unlock groups of lessons at once.
