title: How can I append external DOM to React component?
body: <p>I have a page with a form rendered in the server, it handles validation, and the correct value for the selects.</p>
  
  <p>I want to hide the DOM of that form, and append it into a react component so I can use it in react-router.</p>
  
  <pre><code>const NewItem = React.createClass({  
    render() {                          
      return (                          
        &lt;div&gt;                           
          &lt;h1&gt;New item&lt;/h1&gt;
          {/* I WANT THE FORM FROM THE PAGE HERE*/}
        &lt;/div&gt;                          
      )                                 
    }                                   
  })                                    
  </code></pre>
  
  <p>What is the best way to do it?</p>
