Address Autocomplete Fallback Values
Google Maps does not always provide every data point for an address as some countries are structured differently or a specific neighborhood does. As a result, you sometimes may find a fallback value may be helpful to cover more address scenarios for your users.
As of version 1.6, there is a new fallback feature which allows you to set multiple fallback values to be used in case the primary data point is unavailable. Here is an example:
{locality:long_name fallback="postal_town:long_name"}
If no “locality” value is returned from Google, the Address Autocomplete plugin will then use the value from “postal_town” instead.
You can use multiple fallbacks by separating them with commas:
{locality:long_name fallback="postal_town:long_name,administrative_area_level_1:long_name"}
