I have a list of town names that are associated with a number of regions. Currently the list of towns is around 400 but may grow above more than 2000, so will become problematic in 'choices' tab. I have the towns and regions in a CSV file. What I would like to be able to do is use the CSV to populate a Select_One list with Autocomplete functionality to speed up town name searching.
From reading, I have seen mention of external_selects, but they require a choice filter first. Users of the form do not know region names to be able to filter towns and no other additional information is available apart from these two fields.
Is it possible to use a CSV to populate my select_one list?
