Possibly this has been affected by recent Discourse update (currently on 2.5.0.beta2).
I have a multiselect dropdown feild that was previously set up and working, and set as editable after sign up etc
but now for existing users while contents of this field are displayed in their user profile page, the field is not listed with the other editable custom user fields in their user preferences page.
In other words there is no longer a way for user or administrator to change.
Also, for new users signing up, while the mutiselect field is visible, none of the drop down options are now available/showing (just see a slim blank blue rectangle) - and because this is a set as a mandatory field, sign-up cannot proceed.
Is this a known issue?, and is it confirmed that a Discourse update caused it? Is it known what the most recent compatible Discourse version is - and it there any sensible way to revert to it?
I have posted a report to GitHub, but see that the plugin has not seen any development activity for a couple of years, so not optimistic that a solution will come from that direction. Are there any other (working) ways to achieve a multi-select dropdown for user fields in Discourse?
