Control Positioning

  • This example demonstrates how to customize the positioning of map controls using the Google Maps JavaScript API.

  • You can position controls like zoom and map type selection using mapTypeControlOptions and zoomControlOptions.

  • The provided code snippets showcase this customization in TypeScript, JavaScript, CSS, and HTML.

  • The zoom control is positioned on the left, while the map type control is at the top center of the map.

  • You can explore the sample code via provided links to JSFiddle, Google Cloud Shell, or by cloning and running it locally.

This example demonstrates custom positioning of the map controls. The zoom control options are placed on the left of the map and the map type controls are placed along the top of the map.

TypeScript

const mapElement = document.querySelector('gmp-map')!;
let innerMap: google.maps.Map;

async function init() {
    // Request needed libraries.
    const [{ MapTypeControlStyle }, { ControlPosition }] = await Promise.all([
        google.maps.importLibrary('maps'),
        google.maps.importLibrary('core'),
    ]);

    // Get the inner map.
    innerMap = mapElement.innerMap;

    // Set the map's controls options.
    innerMap.setOptions({
        mapTypeControl: true,
        mapTypeControlOptions: {
            style: MapTypeControlStyle.HORIZONTAL_BAR,
            position: ControlPosition.BLOCK_START_INLINE_CENTER,
        },
        zoomControl: true,
        zoomControlOptions: {
            position: ControlPosition.INLINE_START_BLOCK_CENTER,
        },
        scaleControl: true,
        streetViewControl: true,
        streetViewControlOptions: {
            position: ControlPosition.INLINE_START_BLOCK_START,
        },
        fullscreenControl: true,
    });
}

void init();

JavaScript

const mapElement = document.querySelector('gmp-map');
let innerMap;

async function init() {
    // Request needed libraries.
    const [{ MapTypeControlStyle }, { ControlPosition }] = await Promise.all([
        google.maps.importLibrary('maps'),
        google.maps.importLibrary('core'),
    ]);

    // Get the inner map.
    innerMap = mapElement.innerMap;

    // Set the map's controls options.
    innerMap.setOptions({
        mapTypeControl: true,
        mapTypeControlOptions: {
            style: MapTypeControlStyle.HORIZONTAL_BAR,
            position: ControlPosition.BLOCK_START_INLINE_CENTER,
        },
        zoomControl: true,
        zoomControlOptions: {
            position: ControlPosition.INLINE_START_BLOCK_CENTER,
        },
        scaleControl: true,
        streetViewControl: true,
        streetViewControlOptions: {
            position: ControlPosition.INLINE_START_BLOCK_START,
        },
        fullscreenControl: true,

Clone Sample

Git and Node.js are required to run this sample locally. Follow these instructions to install Node.js and NPM. You will also need a Google Maps API key.

The following commands clone the repository, install dependencies, and copy the environment file. 

  git clone https://github.com/googlemaps-samples/js-api-samples.git
  cd js-api-samples
  npm i
  cp .env.template .env

Once you copy the environment file, make sure to open the .env file and replace <Insert your own development API key here> with your actual API key before starting the sample. 

  cd samples/control-positioning
  npm start
