Thread:Project:Support desk/SubSidebar does not expand (2)/reply (3)

I have just checked the according commit

https://git.wikimedia.org/commitdiff/mediawiki%2Fcore.git/603e6589e7678be099cea50129fde9696ef48c8b

and it does not look like there would be an option to disable this feature.

A nice way would be if it was possible to modify $out->addModules as you can do with the new hook for $out->addModuleStyles, however for addModules I have not seen a hook.

One option might be to add this to the bottom of LocalSettings.php:

unset($wgResourceModules['skins.vector.collapsibleNav']);

This should prevent the skin from loading the collapsiblity-stuff (untested).
