Basic marker customization

Select platform: Android iOS JavaScript

Advanced markers uses two classes to define markers: the AdvancedMarkerElement class provides the basic parameters (position, title, and map), and the PinElement class contains options for further customization. The following snippet shows code to create a new PinElement, then apply it to a marker.

// Create a pin element.
const pin = new PinElement({
    scale: 1.5,
});
// Create a marker and apply the element.
const marker = new AdvancedMarkerElement({
    map,
    position: { lat: 37.419, lng: -122.02 },
    content: pin.element,
});

In maps created using HTML, the basic parameters for a marker are declared using the gmp-advanced-marker HTML element; any customization that uses the PinElement class must be applied programmatically. To do this, your code must retrieve the gmp-advanced-marker elements from the HTML page. The following snippet shows code to query for a collection of gmp-advanced-marker elements, then iterate through the results to apply customization that was declared in the PinElement.

// Return an array of markers.
const advancedMarkers = [...document.querySelectorAll('gmp-advanced-marker')];

// Loop through the markers
for (let i = 0; i < advancedMarkers.length; i++) {
  const pin = new PinElement({
      scale: 2.0,
  });

  marker.appendChild(pin.element);
}

This page shows you how to customize markers in the following ways:

Add title text

Title text appears when the cursor hovers over a marker. Title text is readable by screen readers.

To add title text programmatically, use the AdvancedMarkerElement.title option:


  
  
  
  
  
  

  

     
TypeScript

      
// Default marker with title text (no PinElement).
const markerViewWithText = new AdvancedMarkerElement({
    map,
    position: { lat: 37.419, lng: -122.03 },
    title: 'Title text for the marker at lat: 37.419, lng: -122.03',
});
index.ts

    
    

    

    
JavaScript

      
  
  
  
  
// Default marker with title text (no PinElement).
const markerViewWithText = new AdvancedMarkerElement({
  map,
  position: { lat: 37.419, lng: -122.03 },
  title: "Title text for the marker at lat: 37.419, lng: -122.03",
});
index.js

To add title text to a marker created using HTML, use the title attribute:


  
  
  
  
<gmp-map
  center="43.4142989,-124.2301242"
  zoom="4"
  map-id="DEMO_MAP_ID"
  style="height: 400px"
>
  <gmp-advanced-marker
    position="37.4220656,-122.0840897"
    title="Mountain View, CA"
  ></gmp-advanced-marker>
  <gmp-advanced-marker
    position="47.648994,-122.3503845"
    title="Seattle, WA"
  ></gmp-advanced-marker>
</gmp-map>

Scale the marker

To scale a marker, use the scale option.

TypeScript

// Adjust the scale.
const pinScaled = new PinElement({
    scale: 1.5,
});
const markerViewScaled = new AdvancedMarkerElement({
    map,
    position: { lat: 37.419, lng: -122.02 },
    content: pinScaled.element,
});
index.ts

JavaScript

// Adjust the scale.
const pinScaled = new PinElement({
  scale: 1.5,
});
const markerViewScaled = new AdvancedMarkerElement({
  map,
  position: { lat: 37.419, lng: -122.02 },
  content: pinScaled.element,
});
index.js

Change the background color

Use the PinElement.background option to change the background color of a marker:

TypeScript

// Change the background color.
const pinBackground = new PinElement({
    background: '#FBBC04',
});
const markerViewBackground = new AdvancedMarkerElement({
    map,
    position: { lat: 37.419, lng: -122.01 },
    content: pinBackground.element,
});
index.ts

JavaScript

// Change the background color.
const pinBackground = new PinElement({
  background: "#FBBC04",
});
const markerViewBackground = new AdvancedMarkerElement({
  map,
  position: { lat: 37.419, lng: -122.01 },
  content: pinBackground.element,
});
index.js

Change the border color

Use the PinElement.borderColor option to change the border color of a marker:

TypeScript

// Change the border color.
const pinBorder = new PinElement({
    borderColor: '#137333',
});
const markerViewBorder = new AdvancedMarkerElement({
    map,
    position: { lat: 37.415, lng: -122.03 },
    content: pinBorder.element,
});
index.ts

JavaScript

// Change the border color.
const pinBorder = new PinElement({
  borderColor: "#137333",
});
const markerViewBorder = new AdvancedMarkerElement({
  map,
  position: { lat: 37.415, lng: -122.03 },
  content: pinBorder.element,
});
index.js

Change the glyph color

Use the PinElement.glyphColor option to change the glyph color of a marker:

TypeScript

// Change the glyph color.
const pinGlyph = new PinElement({
    glyphColor: 'white',
});
const markerViewGlyph = new AdvancedMarkerElement({
    map,
    position: { lat: 37.415, lng: -122.02 },
    content: pinGlyph.element,
});
index.ts

JavaScript

// Change the glyph color.
const pinGlyph = new PinElement({
  glyphColor: "white",
});
const markerViewGlyph = new AdvancedMarkerElement({
  map,
  position: { lat: 37.415, lng: -122.02 },
  content: pinGlyph.element,
});
index.js

Hide the glyph

Set the PinElement.glyph option to an empty string to hide a marker's glyph:

TypeScript

// Hide the glyph.
const pinNoGlyph = new PinElement({
    glyph: '',
});
const markerViewNoGlyph = new AdvancedMarkerElement({
    map,
    position: { lat: 37.415, lng: -122.01 },
    content: pinNoGlyph.element,
});
index.ts

JavaScript

// Hide the glyph.
const pinNoGlyph = new PinElement({
  glyph: "",
});
const markerViewNoGlyph = new AdvancedMarkerElement({
  map,
  position: { lat: 37.415, lng: -122.01 },
  content: pinNoGlyph.element,
});
index.js

Alternatively, set PinElement.glyphColor to the same value as PinElement.background. This has the effect of visually hiding the glyph.
