title: Add custom control to a Google Map that's a dropdown
body: <p>I have read the Google Maps V3 API Documentation about <a href="http://code.google.com/apis/maps/documentation/javascript/controls.html#CustomControls" rel="noreferrer">custom map controls</a>.
  This doc shows how to create a simple button. However, what I want to do is create my own drop down menu as a custom control. I want to use this dropdown menu to let the user select a language, like French, or German.</p>
  
  <p>Google provide a built-in map control, called MapType. Further, you can style this control as a dropdown menu by using  the builtin style google.maps.MapTypeControlStyle.DROPDOWN_MENU.</p>
  
  <p>So, by analogy, I want to create a custom control called MapLanguage, and have it use a drop down, as though we had access to something like google.maps.MapLanguageControlStyle.DROPDOWN_MENU. If there's a JQuery way to do this, then, so much the better, as I am already using JQuery elsewhere in my app.</p>
  
  <p>Any pointers to examples would be great.</p>
