The Place Autocomplete sample demonstrates how to use the Place Autocomplete widget to provide a type-ahead search box.
- The radio buttons allow you to filter the types of predictions that the autocomplete returns.
- The Strict Bounds option restricts the search to the area within the current viewport. If this option is not checked, then the API biases the search to the current viewport, but it does not restrict it.
When you select an autocomplete result the sample then calls the getPlace() method, and then it opens an info window to display place details.
For more information, see the Autocomplete class.
