Warning: since sections collapsing behaviour is now integrated into Moodle core, this plugin will not be maintained for Moodle 4.x

The collapsible weeks format is a clone of the core weeks format that adds collapsing behaviour to sections in order to reduce page size. A plugin setting allow to retain topics collapse state on a per user basis for the current session or across sessions. This plugin is an alternative to Gareth J. Barnard's format_topcoll plugin (see references below) The purpose is to offer a simple collapsing behaviour for sections in order to reduce course home page size without all the display options that Gareth's plugin offers.
