Place Autocomplete Restricted to Multiple Countries

This example uses the Place Autocomplete widget to provide a type-ahead search box. The radio buttons allow you to select whether to restrict results to the continental United States, or to include results in the unincorporated organized territories: Puerto Rico, Virgin Islands, Guam and the Northern Mariana Islands.
