title: how to display only + and - in the mapbox navigation control
body: <p>I am using the following code line to show a navigation control on my map:</p>
  
  <pre><code>  map.addControl(new mapboxgl.NavigationControl());
  </code></pre>
  
  <p>It displays the Zoom in + and Zoom out - options which are great but it also shows the tilt map option underneath the zoom in and zoom out buttons. I want to remove this and only show Zoom in and Zoom out option. It seems like something simple to fix but I wasn't able to come up with an anser in my research. </p>
