Hello, maybe I don’t quite understand the documentation : Adding Fields to AdvancedSearch.
I want to put a new field named extra (like the example), the search is good but I have a problem with the label. I put "advancedsearch-optgroup-extra" : "test" in i18n/fr.json and in every other language. In my wiki the result like I don't put an ID:
⧼advancedsearch-optgroup-undefined⧽
⧼advancedsearch-field-undefined⧽
The same for help message : ⧼advancedsearch-field-help-undefined⧽
Any help appreciated.
