title: How to create a dropdown from an icon using Angular Material?
body: <p>I would like to click the alarm icon and that creates a dropdown menu.</p>
  
  <p>I have already seen <a href="https://stackoverflow.com/questions/49746997/angular-material-maticon-in-matselect">this</a></p>
  
  <p>Here is what I have already tried on this <a href="https://stackblitz.com/edit/angular-e7twlq?file=app/select-overview-example.html" rel="nofollow noreferrer">demo</a></p>
  
  <p>I still have the dropdown input box, which I want removed, so I can only see the icon before clicking. I would like it so that it is only the icon and when that gets pressed, it generates the dropdown.</p>
  
  <p>How can I achieve this?</p>
  
  <p>PS: it would be great to see a demo of it on Stackblitz :)</p>
