title: Froala editor disable a button in dropdown?
body: <p>I am using Froala editor in . my application, I want to disable a button in the dropdown of froala editor toolbar.</p>
  
  <p>I have added an option to allow user to <code>align</code> content inside the editor, but I want to disable the 4th(Justify) option in <code>align</code> dropdown in toolbar, keeping only three options (left, centre, right).</p>
  
  <pre><code>FROALA_TOOLBAR_OPTIONS_FLASHCARDS = ['bold', 'italic', 'underline', 'color', '-',
          'formatOL', 'formatUL', 'insertImage', 'align'
      ];
  </code></pre>
  
  <p>I have tried searching through the docs. but didn't found anything useful that will allow me to disable the 4th option in <code>align</code> dropdown in <code>froala</code> toolbar.</p>
