    <div class="google-map"></div>
    <ul class="google-map-markers">
    </ul>
</div>

Initialize Google Map

"use strict";

/**
 * Initialize All Scripts
 */
$document.ready(function () {
    var maps = document.querySelectorAll(".google-map-container");
    if (maps.length) {
        var key;

        for ( var i = 0; i < maps.length; i++ ) {
                if (maps[i].hasAttribute( "data-key" ) ) {
                    key = maps[i].getAttribute( "data-key" );
                    break;
                }
        }

        $.getScript('//maps.google.com/maps/api/js?'+ ( key ? 'key='+ key + '&' : '' ) +'sensor=false&libraries=geometry,places&v=quarterly', function () {
