title: Bootstrap collapse move rest of html body
body: <p>I use bootstrap and make collapse but every time I click on it rest of body go down/up. Is it possible to don't move rest of body?
      This is my example code:</p>
  
  <pre><code>&lt;body&gt;
      &lt;div class="panel-group"&gt;
          &lt;div class="panel panel-default"&gt;
              &lt;div id="collapse1" class="panel-collapse collapse"&gt;
                  &lt;div class="panel-body"&gt;Panel Body&lt;/div&gt;
                  &lt;div class="panel-footer"&gt;Panel Footer&lt;/div&gt;
              &lt;/div&gt;
              &lt;div class="panel-heading"&gt;
                  &lt;h4 class="panel-title"&gt;&lt;a data-toggle="collapse" href="#collapse1"&gt;Collapsible panel&lt;/a&gt;&lt;/h4&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  </code></pre>
