title: How to make an HTML dropdown option not clickable
body: <pre><code>&lt;form action="submit.php" method="post"&gt;
  &lt;select name="input"&gt; 
  &lt;option value="Athletics:"&gt;Athletics:&lt;/option&gt;
  &lt;option value="Running"&gt;Running&lt;/option&gt;
  &lt;option value="Paragliding"&gt;Paragliding&lt;/option&gt;
  &lt;option value="Swimming"&gt;Swimming&lt;/option&gt;
  &lt;/select&gt; 
  &lt;input type="Submit" value="Next"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I'm trying to make "Athletics:" NOT click-able, so users have to choose their specific sport. Help appreciated, thanks. </p>
