title: How can I limit the visible options in an HTML <select> dropdown?
body: <p>How can I limit the number of shown options in an HTML <code>&lt;select&gt;</code> drop down?</p>
  
  <p>For example:</p>
  
  <pre><code>    &lt;select&gt;
      &lt;option value="1"&gt;1&lt;/option&gt;
      &lt;option value="2"&gt;2&lt;/option&gt;
      ...
      &lt;option value="20"&gt;20&lt;/option&gt;
      &lt;/select&gt;
  </code></pre>
  
  <p>How can I get the browser to show only the first five options and scroll down for the rest?</p>
