i have 2 csv files, one for cities and one for streets. i want to enable enter address only from those. give autocomplete and validation according them. i though to upload them into collections(i’ll need to divide them, because they are too long…), but had no idea how to use them in the checkout default process. do you have suggestion for me?
thanks!
