Breaks Dropdown menus

[aspark21]

Openstudio: latest master
Moodle: 3.7.7 and 3.9.1
Other plugins on site: Blackboard Ally set (https://github.com/blackboard-open-source/moodle-tool_ally#additional-plugins) & Adaptable theme (https://gitlab.com/jezhops/moodle-theme_adaptable)

After a couple of misfires with identifying the source of this issue, we are now confident that OpenStudio is the culprit.

What's broken:

• In a course when in editing mode, "Edit" dropdown menus for each activities do not appear
• Site Administration expandable menus don't expand

This seems like what #2 reported but which was lacking detail.

We have been testing a lot of different plugins for start of academic year and the most noticeable impact this was having was javascript errors with Blackboard Ally, which we reported as anthology-ally/moodle-tool_ally#45 which affected the site admin menus , however the "Edit" dropdowns were still broken after removing Ally.

We now have a fully working build with all the other plugins now that we've removed OpenStudio.

Not particularly familiar with how to debug Javascript errors, if there is any test you want us to run happy to, but I've listed repos above for some of the plugins which might be involved in the JS conflicts.

Interesting.. thanks for the detailed report.
Unfortunately I've been unable to replicate the issue. I have downloaded Adaptable 2.2.2 and running on 3.8.4 all the issues you mentioned are not present for me (I tested Adaptable, Boost and Classic themes).
There may be issues with the Ally plugins mentioned, or maybe something specific to the configuration you have setup.

It is worth checking the browser console (F12 key) for reported errors either on page load or when attempting the action that is not working, that sometimes helps narrow down where there are issues.
Generally the Open Studio javascript would not run on other pages, so if it were causing an issue it would be in the source code where all the javascript is compressed into a single file (OS also uses some third party libraries so they could be causing issues on your setup).
