I just upgraded from Django 2.1.3 to 2.2.3, at which point collapsible elements in the admin interface stopped working. I’m using IE11, and in the console I see the error “object doesn't support property or method 'matches'”, with a reference to line 35 of collapse.js in the admin package. I did some research and I found that IE11 doesn’t support the “matches” function, so I just modified the admin base template with a polyfill to get things working on my machine. But the collapsible elements were working fine with my old version of Django on IE11, so it looks like a polyfill (or something) was removed in the most recent Django version. Does anyone know what might have changed? If something was changed, I think this is a bug – we shouldn’t have to modify the templates in the admin package to use IE11.
