If you want to have more than one InfoWindow open at a time you need to create one for each marker (assuming you want them open on all the markers, if you only ever want three, then only create three).
code snippet using a createMarker
function to get closure on the marker/infowindow:
html,
body,
#map {
height: 100%;
width: 100%;
}
