body: <p>I have 3 value for dropdown and i have 2 radio button with name="action"</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">

  <pre class="snippet-code-html lang-html prettyprint-override"><code>Action :
  &lt;select&gt;
    &lt;option value="Further follow up needed"&gt;Further follow up needed&lt;/option&gt;
    &lt;option value="Rejected"&gt;Rejected&lt;/option&gt;
    &lt;option value="Closed"&gt;Closed&lt;/option&gt;
  &lt;/select&gt;
  
  Next Follow Up Date:
  &lt;input name="ww" type="text" id="ww" value=""&gt;&lt;/td&gt;
  &lt;br&gt; Are sure you want to closed the activity?
  &lt;br&gt;
  &lt;INPUT TYPE='radio' NAME='action' VALUE='yes'&gt;Yes
  &lt;INPUT TYPE='radio' NAME='action' VALUE='no'&gt;No</code></pre>
  </div>
  </div>
  </p>
  
  <p>I need to display the radio button if user select 'closed' only, else it will display next follow Up date. (include 'closed' also) </p>
