title: How do I use Jquery to find and select a Multi Select option by the Value?
body: <p>I can't seem to figure out how to correctly select a Multi Select option by the Value and leave the other options that are selected alone. </p>
  
  <p>Update 
  It does work, thanks! I had the multi-select hidden and I thought firebug would update the option to "selected" but it doesn't. When I "show" the multi-select box after setting the attr to selected, it was selected. So that was also part of my problem, what firebug was showing me behind the scene.</p>
