The Place Autocompletesample 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 Boundsoption 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 .

Use the Place Picker component
The place picker component is a text input that allows end users to search for a specific address or place using autocomplete. It is part of the Extended Component Library , a set of web components that help developers build better maps and location features faster.
Use the Place Picker configurator to create embeddable code for a custom Place Picker component, then export it to be used with popular frameworks like React and Angular or no framework at all.
