title: An angular-material-multilevel-menu for Angular 6?
body: <p>I have tried to achieve a multilevel sidenav and I found this that meets my requirements:</p>
  
  <p><a href="https://www.npmjs.com/package/angular-material-multilevel-menu" rel="noreferrer">angular-material-multilevel-menu</a></p>
  
  <p><a href="https://jmouriz.github.io/angular-material-multilevel-menu/demo/demo.html#!/demo/readme" rel="noreferrer">Demo</a> - Note the accordion type</p>
  
  <p>Unfortunately this is created for AngularJS (1.0?), which seems to not work in Angular 6.</p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>Is there any other multilevel sidenav component for Angular 6? Have note found any similar on Google that works.</li>
  <li>Is it possible to "upgrade" this Angular 1.0 menu to Angular 6? How?</li>
  <li>Is there any simple instructions or courses to build your own multilevel side nav? There are many instructions for one-level, but I have found none multi-level.</li>
  </ol>
