title: HTML: Select multiple as dropdown
body: <p>I would like to use a <code>select</code> field with <code>multiple</code> as a common dropdown field with <code>size=1</code>:</p>
  
  <pre><code>&lt;select name="test[]" size="1" multiple&gt;
      &lt;option&gt;123
      &lt;option&gt;456
      &lt;option&gt;789
  &lt;/select&gt;
  </code></pre>
  
  <p>Why doesn't this code show the arrow for the dropdown?</p>
  
  <p>Thanks!</p>
