title: How to show/hide component on click in React-redux?
body: <p>I have a component:</p>
  
  <pre><code>class CommentBox extends Component {
      render() {
          return (
              &lt;div&gt;
                  &lt;p&gt;Some comment&lt;/p&gt;
                  &lt;a&gt;Post a reply to this comment&lt;/a&gt;
              &lt;/div&gt;
              &lt;ReplyForm /&gt;
          )
      }
  }
  </code></pre>
  
  <p>I need this <code>ReplyForm</code> to be hidden on initial load. How to trigger it's state by clicking on a tag?</p>
