title: Add icon to menuItem in JavaFx by CSS
body: <p>I use this CSS to add icon to menuItem on JavaFX application:</p>
  
  <pre><code>    #mniOpen &gt; .label{
      -fx-graphic:url(media/open.png);
  }
  </code></pre>
  
  <p>It works, but one problem: my menuItem has a shortcut key (<kbd>Ctrl+O</kbd>), so in this item there are two label. In the result, the icon repeats twice for this menuItem:</p>
  
  <p><a href="https://i.stack.imgur.com/vdmbX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vdmbX.png" alt="enter image description here"></a></p>
  
  <p>How can remove the second icon (for <kbd>Ctrl+O</kbd>) ?</p>
