title: Summernote insert quote
body: <p>I'm using summernote wysiwyg editor and I need to insert quotes.
  In docs I didn't find way how to insert something like this, I tried with insertNode, but it returns <strong>Uncaught TypeError: Cannot read property 'toUpperCase' of undefined</strong> only way I found that insertNode works only for empty document.createElement.</p>
  
  <p>I've tried with summernote('code', quote); too, but it just replace content. I even tried to create new element, add class and add contents, but still getting same toUpperCase error.</p>
  
  <p>Here is something I've tried already.</p>
  
  <pre><code>function quote(post) {
      var entry   =   $(post),
          author  =   entry.find('.quotable-author').text(),
          date    =   entry.find('.quotable-date').text(),
          content =   entry.find('.quotable-content').html(),
          quote   =   '&lt;blockquote class="quote"&gt;' + content + '&lt;footer&gt;' + author + ' - ' + date + '&lt;/footer&gt;&lt;/blockquote&gt;';
  
      $('.editor').summernote('insertNode', quote);
  }
  </code></pre>
  
  <p>Is this possible to do in summernote or should I search for another wysiwyg editor?</p>
