  <pre><code>&lt;div class="accordion" id="accordionExample"&gt;
    &lt;div class="card"&gt;
      &lt;div class="card-header" id="headingOne"&gt;
        &lt;h5 class="mb-0"&gt;
          &lt;button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne"&gt;
            Collapsible Group Item #1
          &lt;/button&gt;
        &lt;/h5&gt;
      &lt;/div&gt;
  
      &lt;div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample"&gt;
        &lt;div class="card-body"&gt;
