自定義 Bootstrap Navbar 下拉菜單會在屏幕較小時破壞設計

Question

好吧，我有這個 JS Fiddle https://jsfiddle.net/uvkt8z7j/16/每當屏幕很小並且我嘗試單擊右側的下拉菜單時，它似乎破壞了整個設計。 當屏幕為 lrg 時，我希望有相同的行為

  <body style="background-color: black;">
    <div id='header'>
      <nav class="navbar navbar-expand-lg navbar-light bg-light">
        <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>

        <ul class='navbar-nav'>
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

                    </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">

            </div>
          </li>
        </ul>

        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">

        <div class="collapse navbar-collapse" id="navbarNavDropdown">
          <ul class="navbar-nav">
            <li class="nav-item active">
              <a class="nav-link menu-selection" href="#">STORE ORDER ONLINE <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
              <a class="nav-link menu-selection" href="#">STORE INFO</a>
            </li>
            <li class="nav-item">
              <a class="nav-link menu-selection" href="#">STORE LOCATORS</a>
            </li>
          </ul>
        </div>`
      </nav>
    </div>
  </body>

您可以覆蓋引導程序類（在較小的屏幕中）來解決此問題。
請參閱下面演示中的媒體查詢：

 @media screen and (max-width: 992px){ #header .dropdown-menu{ position: absolute; right: 0; left: auto; } }
