title: Changing select's option display style to none under MSIE
body: <p>Could someone please give me a clue as to why the following code does not work under MSIE?</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;select id="si"&gt;
  &lt;option value=""&gt;1&lt;/option&gt;
  &lt;option value=""&gt;2&lt;/option&gt;
  &lt;option value=""&gt;3&lt;/option&gt;
  &lt;/select&gt;
  
  &lt;script type="text/javascript"&gt;
  var e=document.getElementById("si");
  e.size=3;
  e[0].style.display="none"; // &lt;-------- no effect
  &lt;/script&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
