title: Having Issue On Bootstrap 3 SlideDown() hidden Element
body: <p>Can you please take a look at <a href="https://jsfiddle.net/Behseini/zzdL5jp7/" rel="nofollow">this demo</a> and let me know why the <code>change()</code> function is not able to <code>slideDown()</code> a <code>hidden</code> element in Bootstrap 3?</p>
  
  <p>Here is the code I have</p>
  
  <pre><code>$(function() {
      $('input:radio').change(function() {
          if($(this).val()== 'Dog') {
              $('#hidden-list-1').slideDown();
          }
          if($(this).val()== 'Bird'){
              $('#hidden-list-2').slideDown();  
          }
      });
  });
  </code></pre>
