Collapsed topics course format is updated to the Version 184.108.40.206 for Moodle 2.8 (Build: 20141110 and above) by the maintainer Gerath J Barnard.
Collapsed topics course format is a popular course format in the Moodle plugins database which is an interchangeable topic or week based format that solves the issue of the ‘Scroll of Death’ when a course has many topics.
All sections except zero have a toggle that displays that section. One or more sections can be displayed at any given time.
