title: MDC-Web: Multiple simple menu
body: <p>I use google MATERIAL COMPONENTS FOR THE WEB and have problems with the "Simple Menu". Check my codepen: [Multiple menus per page?][1]</p>
  
  <pre><code>[1]: https://codepen.io/QJan84/pen/govRmg
  </code></pre>
  
  <p>The first menu works, the others do not.
  What do I have to do to have multiple menus per page?</p>
