Google Maps Javascript two InfoWindow for the same marker

stiGVicious

I would like to add an infoWindow that is always visible (like the title label but always visible) and another which is shown when the user clicks on the marker (aka the normal behavior). Currently my for loop for adding the markers look like this:

for (i = 0; i < markers.length; i++) {
        var data = markers[i];
        var icon = "";
        icon = "/images/map-icon.png";
        var position = new google.maps.LatLng(data.lat, data.lng);
        bounds.extend(position);
        marker = new google.maps.Marker({
            position: position,
            map: map,
            title: data.title,
            icon: new google.maps.MarkerImage(icon)
        });

        (function (marker, data) {
            google.maps.event.addListener(marker, "click", function (e) {
                infoWindow.setContent(data.description);

                infoWindow.open(map, marker);
            });
        })(marker, data);

        map.fitBounds(bounds);
        map.setCenter(bounds.getCenter());
        map.fitBounds(bounds);
    }

One option: Create a fixed InfoWindow for each marker, opened when created, then one dynamic InfoWindow with the "normal" InfoWindow behavior which opens on top of the fixed InfoWindow.

for (i = 0; i < markers.length; i++) {
  var data = markers[i];
  var position = new google.maps.LatLng(data.lat, data.lng);
  bounds.extend(position);
  marker = new google.maps.Marker({
    position: position,
    map: map,
    title: data.title,
  });
  // fixed always open InfoWindow
  marker.iw = new google.maps.InfoWindow();
  marker.iw.setContent(data.title);
  marker.iw.open(map, marker);

  // dynamic InfoWindow, opened on click
  (function(marker, data) {
    google.maps.event.addListener(marker, "click", function(e) {
      infoWindow.setContent(data.description);
      infoWindow.open(map, marker);
    });
  })(marker, data);

  map.fitBounds(bounds);
}

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 10,
    center: {
      lat: -33.9,
      lng: 151.2
    }

  setMarkers(map);
}

var markers = [{
