Is there a way to filter a select one list that is using appearance search that has more than the maxRecCount based on the first character typed into the question? For instance if I have a select_one question that is based on a feature layer of street names, can I filter the list based on the first character that is typed into the question, like street names that begin with the letter "R"?
You can combine the search appearance with autocomplete (even recommended here https://community.esri.com/t5/arcgis-survey123-blog/dynamic-choice-lists-using-search-appearance/ba-...). In one of the comments I saw that you just put "autocomplete search(...)" as appearance. Is that what you need?
