折叠导航栏将不可折叠的项目从导航栏移开

Question

我有这个导航栏：

如果屏幕变小，购物车大军不应该折叠：

到目前为止，一切都很好......

但是，当我点击切换按钮时，我的购物车大军也随着菜单向下移动，如下所示：

但我希望我的购物车大军也能熬夜，就像这张图片（现在画的）：

我已经找了几个小时了，但仍然无法实现这种行为。这是fiddle。

代码：

<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
    <a class="navbar-brand" href="#">English Park Cuisine</a>
    <button class="navbar-toggler" 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>
    <div class="collapse navbar-collapse" id="navbarNavDropdown">
        <ul class="navbar-nav ml-auto">
            <li class="nav-item active">
                <a class="nav-link" href="index.php">Acasa<span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                Meniu
                </a>
                <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
                    <a class="dropdown-item" href="meniu.php">Pizza</a>
                    <a class="dropdown-item" href="#">Paste</a>
                    <a class="dropdown-item" href="#">Supe</a>
                    <a class="dropdown-item" href="#">Ciorbe</a>
                    <a class="dropdown-item" href="#">Desert</a>
                </div>
            </li>
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Contact</a>
                <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
                    <p class="dropdown-item">0746117702</p>
                    <p class="dropdown-item">0742112452</p>
                    <p class="dropdown-item">0735212352</p>
                </div>
            </li>
        </ul>
    </div>

    <div class="d-flex order-lg-1 ml-auto pr-2">
        <a href="#" class="navbar-text"><i class="fa fa-shopping-cart fa-lg" style="color: white;"></i></a>
        <a href="#" class="navbar-text"><i class="fa fa-shopping-cart fa-lg" style="color: white;"></i></a>
        <a href="#" class="navbar-text"><i class="fa fa-shopping-cart fa-lg" style="color: white;"></i></a>           
    </div>

</nav>

这个问题与this one 非常相似，但是，你看不到这种行为，因为导航栏的顺序不同，这就是这个问题的独特之处。

Answer 1

您可以使用order-* classes 来解决此问题。只需将要保留在顶部导航栏上的项目的顺序value 保持在低于切换折叠模式的button 的值即可。在下一个示例中：

(1) 当导航栏未折叠时（lg 屏幕），购物车大军将拥有 order-4 并排在最后。

(2) 折叠导航栏时，购物车大军将显示order-1，切换折叠按钮将显示order-2。所以折叠按钮不会影响它。

Answer 2

试试这个：

<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
    <a class="navbar-brand" href="#">English Park Cuisine</a>

    <div class="d-flex order-lg-1 ml-auto pr-2" style="margin-right:20px;">
        <a href="#" class="navbar-text"><i class="fa fa-shopping-cart fa-lg" style="color: white;"></i></a>
        <a href="#" class="navbar-text"><i class="fa fa-shopping-cart fa-lg" style="color: white;"></i></a>
        <a href="#" class="navbar-text"><i class="fa fa-shopping-cart fa-lg" style="color: white;"></i></a>

    </div> 
            <button class="navbar-toggler" 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>
