I am trying to create a moodle course format just like moodle topics format which will dynamically load topics/sections and not all at once. I need some headstart for the same.I am trying to load course sections dynamically because I want to handle condition where there will be more than 100 course sections and loading those amount of sections on one go will cause session lock error for user.
I checked few course formats on moodle plugins directory for the same but could not find any.
There is a contributed plugin called "Collapsed Topics"
The contents are hidden until the student clicks the drop down arrow to reveal the content
