Make markers clickable and accessible | Maps JavaScript API

Stay organized with collections Save and categorize content based on your preferences.

You can make markers more accessible by enabling click event handling, adding descriptive text for screen readers, and adjusting the marker scale.

• When a marker is clickable (or draggable), it can respond to keyboard and mouse input.
• Text specified in the title option is readable by screen readers, and will display when a user holds the mouse pointer over the marker.
• Increasing the size of markers reduces the precision required to interact with it across all devices — especially touchscreen devices — and improves accessibility. Default markers meet the WCAG AA minimum size standard but for developers aiming to comply with the WCAG AAA target size standard the marker size should be increased.

See basic marker customization to learn how to change marker scale, add title text, and more.

The following example shows a map with five clickable, focusable markers that include title text, and have been set to 1.5x scale:

1. Use the tab key to focus on the first marker; if there are multiple markers on the same map, use the arrow keys to cycle through the markers.
2. If the marker is clickable, press the enter key to "click". If a marker has an info window, you can open it by clicking, or by pressing the enter key or space bar. When the info window closes, focus will return to the associated marker.
3. Press tab again to continue moving through the rest of the map controls.

This section shows you how to make markers respond to click events. To make a marker clickable:

• Set the gmpClickable property to true.

const marker = new AdvancedMarkerElement({
    position,
    map,
    title: `${i + 1}. ${title}`,
    content: pin.element,
    gmpClickable: true,
});

const marker = new AdvancedMarkerElement({
    position,
    map,
    title: `${i + 1}. ${title}`,
    content: pin.element,
    gmpClickable: true,
});

• Add a click event listener to respond to user input.

// Add a click listener for each marker, and set up the info window.
marker.addListener('click', ({ domEvent, latLng }) => {
    const { target } = domEvent;
    infoWindow.close();
    infoWindow.setContent(marker.title);
    infoWindow.open(marker.map, marker);
});

// Add a click listener for each marker, and set up the info window.
marker.addListener('click', ({ domEvent, latLng }) => {
    const { target } = domEvent;
    infoWindow.close();
    infoWindow.setContent(marker.title);
    infoWindow.open(marker.map, marker);
});

• To make a marker unclickable again, call removeListener to remove the click event listener:

  // Remove the listener.
  google.maps.event.removeListener(clickListener);
  

To further enhance accessibility:

• Set descriptive text for a marker using the AdvancedMarkerElement.title option.
• Increase marker scale using the scale property of PinElement.

async function initMap() {
    // Request needed libraries.
    const { Map, InfoWindow } = await google.maps.importLibrary("maps") as google.maps.MapsLibrary;
    const { AdvancedMarkerElement, PinElement } = await google.maps.importLibrary("marker") as google.maps.MarkerLibrary;
