title: HTML Select Box show as Multiple, but to Disable Multiple Selection?
body: <p>I needed to have:</p>
  <ul>
  <li>A html <code>&lt;select&gt;</code> box showing as a vertically expanded box (not a Dropdown). So i set it as <code>multiple</code>.</li>
  </ul>
  <p>Then it is showing correctly as:<br></p>
  <pre><code>&lt;select id=&quot;gagaga&quot; multiple&gt;
      &lt;option&gt;A&lt;/option&gt;
      &lt;option&gt;B&lt;/option&gt;
      &lt;option&gt;C&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  <p>How can i make it non-multiple selectable (to allow only 1 selection)?</p>
