TypeScript

// You can set control options to change the default position or style of many
// of the map controls.

async function initMap() {
    //  Request the needed libraries.
    await google.maps.importLibrary('maps');

    const mapElement = document.querySelector(
        'gmp-map'
    ) as google.maps.MapElement;

    const innerMap = mapElement.innerMap;

    innerMap.setOptions({
        mapTypeControl: true,
        mapTypeControlOptions: {
            style: google.maps.MapTypeControlStyle.DROPDOWN_MENU,
            mapTypeIds: [
                google.maps.MapTypeId.ROADMAP,
