title: QuillJS Reload toolbar controls
body: <p>I am using QuillJS and I need to add some controls to toolbar during runtime. Is there any way to make it from code after whole Quill has been initialized?</p>
  
  <p>This is how I make it now.</p>
  
  <pre><code>quillEditor.getModule('toolbar').addHandler('color', (value) =&gt; {
      if (value == 'new-color') {
          value = prompt('Give me hex color baby!');
  
          // unfortunately this code does not work    
          let n = toolbar.querySelector('select.ql-color');
          n.innerHTML += '&lt;option value="'+value+'"&gt;&lt;/option&gt;';
      }
  
      quillEditor.format('color', value);
      console.log("Color handler", value);
  });
  </code></pre>
