Boost theme
From MoodleDocs
Boost is the default theme for recent Moodle sites.
- Boost is easy to configure using industry-standard Bootstrap presets, with Bootstrap 4, built-in SASS compiler, automated RTL support, preset files, new templates which make it easier to customise Moodle components. Share your presets on MoodleNet.
- Note that Boost does not support submenus in the custom menu setting.
