      &lt;div class="panel-heading"&gt;
          &lt;h4 class="panel-title"&gt;
              &lt;a data-toggle="collapse" data-parent="#accordion1" href="#collapseOne"&gt;
                  Collapsible Group Item #1
              &lt;/a&gt;
          &lt;/h4&gt;
      &lt;/div&gt;
      &lt;div id="collapseOne" class="panel-collapse collapse"&gt;
          &lt;div class="panel-body"&gt;Panel 1&lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="panel panel-default"&gt;
      &lt;div class="panel-heading"&gt;
          &lt;h4 class="panel-title"&gt;
              &lt;a data-toggle="collapse" data-parent="#accordion1" href="#collapseTwo"&gt;
                  Collapsible Group Item #1
              &lt;/a&gt;
          &lt;/h4&gt;
      &lt;/div&gt;
      &lt;div id="collapseTwo" class="panel-collapse collapse"&gt;
          &lt;div class="panel-body"&gt;Panel 2&lt;/div&gt;

  &lt;/div&gt;
  &lt;div class="divWhichIWantHide"&gt;

          &lt;div id="collapseThree" class="panel-collapse collapse"&gt;
              &lt;div class="panel-body"&gt;Panel 3&lt;/div&gt;
          &lt;/div&gt;
