title: how to use pattern attribute allowing some strings as well
body: <p>I am using the pattern: <code>[s]{1}[1-9]{1,6}</code></p>
  
  <p>I am trying to match these conditions:</p>
  
  <ul>
  <li>It should start with <code>s</code></li>
  <li>Followed by numeric characters (with maximum 6 digits)</li>
  <li>Blank not allowed</li>
  </ul>
  
  <p>It's working fine at the moment, but how can I also allow a few specific values in this regex, e.g. "admin", "superAdmin"?</p>
