Hi, you would need to check Google maps API https://developers.google.com/maps/do.... Here you can find the list of supported by Google maps features and detailed description on how to implement it.

Hello! I put this code but I don't load de map!

var map;
var chicago = new google.maps.LatLng(38.845, -0.468);

function HomeControl(controlDiv, map) {

controlDiv.style.padding = '5px';

var controlUI = document.createElement('div');
controlUI.style.backgroundColor = 'white';
controlUI.style.borderStyle = 'solid';
controlUI.style.borderWidth = '2px';
controlUI.style.cursor = 'pointer';
controlUI.style.textAlign = 'center';
controlUI.title = 'Click to set the map to Home';
controlDiv.appendChild(controlUI);

// Set CSS for the control interio
var controlText = document.createElement('div');
controlText.style.fontFamily = 'Arial,sans-serif';
controlText.style.fontSize = '12px';
controlText.style.paddingLeft = '4px';
controlText.style.paddingRight = '4px';
controlText.innerHTML = 'Home';
controlUI.appendChild(controlText);

google.maps.event.addDomListener(controlUI, 'click', function() {
map.setCenter(chicago)
});

}

function initialize() {
var mapDiv = document.getElementById('googlemap_1');
var myOptions = {
zoom :10,
center: new google.maps.LatLng(38.845, -0.468),
mapTypeId: google.maps.MapTypeId.ROADMAP
};

var map = new google.maps.Map($('div[dsid="googlemap_1"]').get(0), myOptions);

var homeControlDiv = document.createElement('div');
var homeControl = new HomeControl(homeControlDiv, map);

homeControlDiv.index = 1;
map.controls[google.maps.ControlPosition.TOP_RIGHT].push(homeControlDiv);
}

google.maps.event.addDomListener(window, 'load', initialize);

Hi Laura,

Sorry, no news yet. We are working on it.

You have few errors. Try this code:
