I have two custom fields: Author and Language, and they are dropdown in the map filter.
Each marker has an author and a language.
When selecting a language, is there a possibility that only the corresponding authors appear in the dropdown?
Another thing, would you like to have an option in the dropdown of “all”, showing all the markers?
Thank you so much for getting in touch, we really appreciate your time.
Unfortunately, this is not currently possible and would require large core code changes in order to allow for such a feature. We have added this to our development plans to perhaps be looked into and implemented in a future update.
Instead of having an “All” field in the dropdown, instead, there is the reset switch which allows a user to simply click reset which then displays all the markers once more.
