I am trying to have a Radio Buttons (Yes and No). The Radio Button with label "No" is default. When I click on the "Yes" button, I need to show a comment box where I can type text and also add hyper links. How to show a comment box when "Yes" is clicked.

Below is my code view snippet.

<div class="row">
  <div class="col-lg-4 appRightLabels">
      <label>Exception Provided</label>
  </div>
  <div style="margin-top:17px">
      <ul class="fieldlist">
          <li>
              @(Html.Kendo().RadioButtonFor(m=>Model.data.FirstOrDefault().IsRequired).Label("Yes").Value(true).Checked(Model.data.FirstOrDefault().IsRequired == true))
          </li>
          <li>
              @(Html.Kendo().RadioButtonFor(m=>Model.data.FirstOrDefault().IsRequired).Label("No").Value(false).Checked(Model.data.FirstOrDefault().IsRequired == false))
          </li>
      </ul>
  </div>
</div>
