title: Can I style a <select> element to show columns?
body: <p>I'm trying to create a column-based list within a  &lt;select&gt; element with multiple=multiple - what I'd like to see in the menu is:</p>
  
  <pre><code>Opt1    Opt5    Opt9
  Opt2    Opt6    Opt10
  Opt3    Opt7    Opt11
  Opt4    Opt8    Opt12
  </code></pre>
  
  <p>Is this possible? I'm certainly open to doing this in jQuery but would prefer CSS.</p>
