When you mean “filter” do you mean using https://meta.discourse.org/filter? And “topic language” do you mean original written language by the author?
I was more thinking the ability to filter which topics are visible while browsing the forum.
For instance, on our forum ( https://forum.commown.coop ) with the Multilingual plugin activated, once logged in, you could set Content languages in your Profile → Interface options to which options you wished to display.
I wasn’t aware of the /filter page - if it were possible to filter topics based on the set topic locale field, this could be a nice alternative c:
By “topic language”, I meant the locale field on posts :
Edit:
- I precised that the topic filter is a feature from the Multilingual plugin
- As a precision, the Multilingual plugin uses tags, by considering locale tags (
fr,de,en) as a seperate field, then probably filters topics with the given tag (I haven’t looked at the filtering code in detail)
