How to add accordion in CKEditor jQuery Ajax?

Question

This is my HTML code

  <div class="row">
   <div class="col-md-12">
    <div class="form-group">
        <label style="font-size:14px;" class="control-label">Roles and Responsibilities: 
        </label>

        <div class="col-md-12">
            <textarea rows="4" style="width:100%;" name="detail" id="detail"></textarea>
        </div>
        <span style="color:red;font-size:12px;" id="jobmsg9"></span>
     </div>
  </div>
</div>  

This is the JQuery ajax part-

  CKEDITOR.replace('detail', {});

This is CDN of CKEditor-

  <script src="https://cdn.ckeditor.com/4.15.0/standard/ckeditor.js"></script>
  <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
