Setting Marker Icons
To customize a marker icon, you can set either a string or an array of options (opens new window).
- As a string - Specify only the path to your marker icon file.
map.markers(locations, {
'icon': '/path/to/marker.png'
});
- As an array of options - Specify an array of parameters from Google's native Icon interface (opens new window).
map.markers(locations, {
'icon': {
'url': '/path/to/marker.png'
}
});

# Control the size of a marker icon
Configure the icon as an array, specifying scaledSize
to control the marker size.
// Specify the dimensions of a marker icon
map.markers(locations, {
'icon': {
'url': '/path/to/marker.png',
'scaledSize': {'width': 30, 'height': 40}
}
});
# Set icons for a batch of markers
If you've got multiple groups of markers, you can specify a different icon for each batch of markers.
// Get all bars & restaurants
const bars = {'lat': 37.2430548, 'lng': -115.7930198}; // Coords only in JS
const restaurants = {'lat': 57.3009274, 'lng': -4.4496567}; // Coords only in JS
// Create a dynamic map (with no markers)
const map = googleMaps.map();
// Add all bar markers
map.markers(bars, {
'icon': '/images/bar-icon.png'
});
// Add all restaurant markers
map.markers(restaurants, {
'icon': '/images/restaurant-icon.png'
});
// Display map (inject into `#my-map-container`)
map.tag({'parentId': 'my-map-container'});
# Set icon for an existing marker
It's also possible to change the icon of an existing marker:
map.setMarkerIcon(markerId, icon);
Marker ID formula
The default formula for a markerId
is as follows:
'[ELEMENT ID]-[FIELD HANDLE]' // eg: '101-myAddressField'
Read more about the setMarkerIcon
method.
Get the Marker IDs
To see the existing marker IDs (if you didn't manually specify them), do the following:
- Put the site into devMode (opens new window).
- View the JS console while the map is being rendered.
In the JavaScript console, you should see a complete play-by-play of every map component being created. Simply copy & paste the marker ID's you need from there, or take note of the pattern for your own needs.
