PlaceID Finder

Read the documentation or view this example full screen.

// This sample uses the Place Autocomplete widget to allow the user to search
// for and select a place. The sample then displays an info window containing
// the place ID and other information about the place that the user has
// selected.

// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">
