How Can I Customize Google Maps InfoWindow Presentation?

Customizing Google Maps InfoWindow Presentation

Styling an InfoWindow in Google Maps can pose a challenge due to limited documentation. Fortunately, various approaches exist to achieve the desired customization:

InfoBubble Class

Google provides the InfoBubble class as an alternative to InfoWindow. InfoBubble is highly stylable, allowing you to customize its appearance through properties such as backgroundColor, borderRadius, and arrowStyle. Here's an example:

infoBubble = new InfoBubble({
  map: map,
  content: '<div class="mylabel">The label</div>',
  position: new google.maps.LatLng(-32.0, 149.0),
  backgroundColor: 'rgb(57,57,57)',
  borderRadius: 5,
  arrowSize: 10
});

infoBubble.open();

Info Window Custom (OverlayView)

Another approach is to extend the Google Maps API's GOverlay class and use it as the basis for a customized info window. This method provides greater flexibility and requires implementing methods such as createElement, draw, and panMap:

/* An InfoBox is like an info window, but it displays
 * under the marker, opens quicker, and has flexible styling.
 */
function InfoBox(opts) {
  google.maps.OverlayView.call(this);
  this.latlng_ = opts.latlng;
  this.map_ = opts.map;
  ...
}

InfoBox.prototype = new google.maps.OverlayView();

Note that overriding the required methods is necessary to create a fully functional custom info window using this approach.

Modifying InfoWindow Elements with JavaScript

You can also modify the elements of the InfoWindow dynamically using JavaScript (or jQuery). By manipulating elements in the InfoWindow, you can achieve some degree of customization.
