This widget is powered by the Places Autocomplete library from the Google Maps API. This address autocomplete text field is designed to make it easier for users to enter an address.
Address entry is time consuming. The Google Places Autocomplete API helps you reduce form friction by providing a single, quick input field with address prediction that can be used to automatically populate billing or shipping addresses in your forms.
When the user starts typing in that field, a list of predictions will be displayed below the field based on what they typed. You can also select which address elements to autocomplete.
