title: Add items to end of selectlist
body: <p>I need to manually add a few items to the end of a selectlist that was already created.  Here is the code for the selectlist:</p>
  
  <pre><code>m.StateList =
      new SelectList(svc.GetStates(user.Login, user.Password), "Key", "Value");
  </code></pre>
  
  <p>Can someone tell me how I can add a few more items to that list? I have done plenty of searching.</p>
