Модуль ajax contact в модальном окне (Joomla)

Добрый день! В данный момент используем компонент SP Page Builder. В данном расширении есть аддон под названием ajax contact, который мы активно используем в формах на странице. Требуется добавить в модальное окно форму с этим аддоном.

Модальное окно:

<div id="myModal" class="modal fade"> 
    <div class="modal-dialog"> 
        <div class="modal-content"> 
            <!-- Заголовок модального окна --> 
            <div class="modal-header"> 
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button> 
                <h4 class="modal-title">Форма обратной связи</h4> 
            </div> 
            <!-- Основное содержимое модального окна --> 
            <div class="modal-body"> 
            </div> 
            <!-- Футер модального окна --> 
            <div class="modal-footer"> 
                <button type="button" class="btn btn-default" data-dismiss="modal">Закрыть</button> 
            </div> 
        </div> 
    </div> 
</div>
