title: creating a Placemarks that can be hidden
body: <p>I have been trying to create a Placemark that I can hide and show (like turning visibility on and off) on demand (on click)... I am using this to make the placemark:</p>
  
  <pre><code>function placemark(lat, long, name, url, iconsrc){
      var placemark = ge.createPlacemark(name);
      ge.getFeatures().appendChild(placemark);
      placemark.setName(name);
  
      // Create style map for placemark
      var icon = ge.createIcon('');
      if(iconsrc == "0")
          icon.setHref('http://maps.google.com/mapfiles/kml/paddle/red-circle.png');
      else{
          icon.setHref(iconsrc);
      }
      var style = ge.createStyle('');
      style.getIconStyle().setIcon(icon);
      if(iconsrc != "0")
          style.getIconStyle().setScale(2.5);
  
      placemark.setStyleSelector(style);
  
      // Create point
      var point = ge.createPoint('');
      point.setLatitude(lat);
      point.setLongitude(long);
      //point.setAltitudeMode(1500);
      placemark.setGeometry(point);
      google.earth.addEventListener(placemark, 'click', function(event) {
      // Prevent the default balloon from popping up.
          event.preventDefault();
  
          var balloon = ge.createHtmlStringBalloon('');
          balloon.setFeature(placemark); // optional
          balloon.setContentString(
              '&lt;iframe src="'+ url +'" frameborder="0"&gt;&lt;/iframe&gt;');
  
          ge.setBalloon(balloon);
      });              
  
  }
  </code></pre>
  
  <p>I have tried everything... from this:</p>
  
  <pre><code>function hidePlacemark(name){
      var children = ge.getFeatures().getChildNodes();
      for(var i = 0; i &lt; children.getLength(); i++) { 
          var child = children.item(i);
          if(child.getType() == 'KmlPlacemark') {
              if(child.getId()== name)
              child.setVisibility(false);
          }
      }
  }
  </code></pre>
  
  <p>to using this <code>ge.getFeatures().removeChild(child);</code></p>
  
  <p>can anyone point me to the right direction on creating a function that will allow me to turn the visibility on/off on demand please.</p>
