Is it possible to have the same thing as this example?
example

function toggleGroup(type) {
  for (var i = 0; i < markerGroups[type].length; i++) {
    var marker = markerGroups[type][i];
    if (!marker.getVisible()) {
      marker.setVisible(true);
    } else {
      marker.setVisible(false);
    }
  }
}

I can find any maps created by geo mashup with metabox to hide or show the marker 🙁

Thanks
