Add your forms html in the [html.trusted] shortcode.

add the “data-safe_id='[app.safe_id /]’” attribute to your all form elements scripts and form tag itself.

Sample:

[html.trusted]
  <form data-safe_id='[app.safe_id /]' class="sample-form" method="post" novalidate>
    <div class="form-group">
      <div class="label-wrapper">
        <label class="field-label">Enter Name</label>
      </div>
      <div class="field-wrapper">
        <input type="text" name="name" class="form-control" placeholder="Enter Name" data-safe_id='[app.safe_id /]'>
        <p class="help-block"></p>
      </div>
    </div>

    <div class="form-group">
