List of suggestions for a custom field
Ok guys, I'm looking for a way to add a list of city suggestions to the custom field 'City'.
i.e. To post a ad, the user have to type the city name in the custom field, instead, would be much better if he could choose from a list, so if he type the letter S for example a list with cities starting with S would appear and he must choose one.
Any help? Thank you.
