위임된 이벤트 핸들러 기능을 유지하면서 내부 클릭 시 부트스트랩 드롭다운이 닫히는 것을 방지하는 방법은 무엇입니까?

<code class="html"><ul class="nav navbar-nav">
  <li class="dropdown mega-dropdown">
    <a href="javascript:;" class="dropdown-toggle" data-toggle="dropdown">
      <i class="fa fa-list-alt"></i> Menu item 1
      <span class="fa fa-chevron-down pull-right"></span>
    </a>
    <ul class="dropdown-menu mega-dropdown-menu">
      <li>
        <div id="carousel" class="carousel slide" data-ride="carousel">
          <!-- Carousel content -->
        </div>
      </li>
    </ul>
  </li>
</ul></code>

<code class="javascript">$('ul.dropdown-menu.mega-dropdown-menu').on('click', function(event){
    // The event won't be propagated up to the document NODE and 
    // therefore delegated events won't be fired
    event.stopPropagation();
});</code>

<code class="javascript">$(document).on('click', 'someyourContainer .dropdown-menu', function (e) {
  e.stopPropagation();
});</code>
