Hi Moodlers,
I have released a stable Collapsed Topics for Moodle 3.1: https://moodle.org/plugins/pluginversion.php?id=11348.
It contains:
Version 3.1.1
1. First stable version for Moodle 3.1.
Version 3.1.0.1
1. Alpha version for Moodle 3.1.
2. Refactor to use spans instead of links for the toggle for MDL-51802 as cannot have a link in a link.
3. Implement MDL-51802.
Cheers,
Gareth
