Styled Map Selection

This example applies custom styles to a map by setting MapOptions.styles to a JSON object containing style declarations. Select an option to see some of the customizations you can apply with map styling. One of the options shows you how to hide features, in this case by removing business points of interest and public transport icons from the map.

Find out more about custom styling in the documentation. You can also view this example full screen.

var map;
function initMap() {
  // Create the map with no initial style specified.
  // It therefore has default styling.
  map = new google.maps.Map(document.getElementById('map'), {
    center: {lat: -33.86, lng: 151.209},
    zoom: 13,
    mapTypeControl: false
  });

  // Add a style-selector control to the map.
  var styleControl = document.getElementById('style-selector-control');
  map.controls[google.maps.ControlPosition.TOP_LEFT].push(styleControl);

  // Set the map's style to the initial value of the selector.
  var styleSelector = document.getElementById('style-selector');
  map.setOptions({styles: styles[styleSelector.value]});

  // Apply new JSON when the user selects a different style.
  styleSelector.addEventListener('change', function() {
    map.setOptions({styles: styles[styleSelector.value]});
  });
