Make markers clickable and accessible

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

When a marker is clickable or draggable, it can respond to keyboard and mouse input. You can use the mouse or keyboard to move between markers, and to move a marker if it's draggable. Text specified in the title option is visible to screen readers.

  • To make a marker clickable, add a click event handler.
  • To make a marker draggable, set the AdvancedMarkerView.draggable property to true.
  • To set descriptive text for a marker, use the AdvancedMarkerView.title option.

Make a marker clickable

The following example shows a map with five clickable, focusable markers:

To navigate markers using the keyboard:

  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.

Try Sample

To make a marker unclickable again, remove the click event listener:

// Adding the listener.
const clickListener = markerView.addListener('click', () => {...});

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

Make a marker draggable

When draggability is enabled, users can drag markers on the map using the mouse or the arrow keys. To make a marker draggable, set the AdvancedMarkerView.draggable property to true.

The following example map shows a draggable marker that displays its updated position when dragging is finished (the dragend event is fired):

To drag a marker with the keyboard:

  1. Press the tab key until markers are focused.
  2. Use the arrow key to move to the desired marker.
  3. To activate dragging, press Option + Space or Option + Enter (Mac), ALT + Space or Alt + Enter (Windows).
  4. Use the arrow keys to move the marker.
  5. To drop the marker at its new location, press Space or Enter. This will also turn dragging off.
  6. To turn dragging off and return the marker to its previous position, press Esc.

Set descriptive text

To set descriptive text for a marker, which can be read by screen readers, use the AdvancedMarkerView.title attribute, as shown here:

    const markerView = new google.maps.marker.AdvancedMarkerView({
        map,
        position: { lat: 37.4239163, lng: -122.0947209 },
        title: "Some descriptive text.",
    });

When the title attribute is set, the text is visible to screen readers, and will appear when the mouse hovers over the marker.
