Here's an example of React + jQuery UI sortable. The key thing to note is that we have the render() method do absolutely nothing and use componentDidUpdate() + React.renderComponent() to proxy updates through to the children. This lets us manage the DOM manually but still be able to use all the React goodies you know and love.
