There are five possible ribbons or banners for Courses that will appear on the Public site. These are meant to highlight courses based on certain criteria that is hard coded in the system.
Waitlist will automatically appear as a ribbon on any course that has all sections full with the waitlist option enabled and that is active for enrollment.
Full will automatically appear as a ribbon on any course that has all sections full with no waitlist option enabled.
Starting Soon will automatically appear as a ribbon on any course that currently has sections open for registration and has additional sections starting within five days.
New will automatically appear as a ribbon on any course that has a course section that has just come online. The ribbon stays visible for three days from the online registration start date.
Popular will automatically appear as a ribbon on any course that is currently experiencing the highest number of enrollments. The algorithm this ribbon uses takes into account factors like how close timewise the enrollments are occurring, how full the course is and how long the course has been open for online registration along with other factors.
The ribbons appear automatically. There is not any way to customize, change or disable them.
