title: Draft.js how to represent list of items?
body: <p>In order to create image carousel, I thought creating nested blocks as following</p>
  
  <ul>
  <li>image_carousels
  
  <ul>
  <li>image</li>
  <li>image</li>
  <li>image</li>
  </ul></li>
  </ul>
  
  <p>Then I found draft.js doesn't support nested blocks. (<a href="https://github.com/facebook/draft-js/issues/143" rel="nofollow noreferrer">https://github.com/facebook/draft-js/issues/143</a> they say draft.js is flat) </p>
  
  <p>But on the other hand, there's UL/OL and LI , that's like group and element structure.</p>
  
  <p>Is there a way to group elements/components/blocks so that we can render the whole + individual (such as we render carousel with individual images)</p>
