title: Making different groups/layers for with markers on Google Maps
body: <p>I just started using the Google Maps API, but I am using it through a asp.net control <a href="http://googlemap.codeplex.com/" rel="nofollow">http://googlemap.codeplex.com/</a> </p>
  
  <p>But I am a bit in doubt, is it possible for me create categories / layers (Some sort of collection) where I can put markers on, and then have a Checkbox for each category to show/hide it or should I do that in code behind</p>
