title: Ionic navbar dropdown-menu
body: <p>I'd like to have an icon (three-bars) on the right-side in the navbar.</p>
  
  <p>Something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/9ogEG.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9ogEG.png" alt="enter image description here"></a></p>
  
  <p>I used to have it, I found the code somewhere on the internet, but I lost my code and I couldn't find again the URL from which I learned the technique.</p>
  
  <p>Please help me recover the technique.</p>
  
  <p>Thanks!</p>
