带 2 行的 Bootstrap 4 导航栏

Question

我使用 Bootstrap 4 alpha 6 创建了一个导航栏，左侧有一个大品牌/图标，图标右侧有 2 个导航栏导航。一个导航有链接，另一个导航有图标。它完全按照我的意愿工作，除了一件事。

我希望 2 个导航栏出现在图标右侧的 2 个单独的行中。像这样：

------------------------------------------------------
               link link link link  
brand-icon -------------------------------------------
               icon icon icon
------------------------------------------------------

移动版仍会像现在一样垂直显示链接。我用 flexbox 尝试了几种不同的方法，但无法让它工作。

这是我的代码：

<nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse">
    <div class="container">
        <button class="navbar-toggler navbar-toggler-right align-self-center mt-3" type="button" data-toggle="collapse" data-target="#navbarCollapse">
            <span class="navbar-toggler-icon"></span>
        </button>
        <h1 class="py-2 ml-lg-2 mx-3"><a href="#"><i class="fa fa-envelope-open-o fa-lg" aria-hidden="true"></i></a></h1>
        <div class="collapse navbar-collapse ml-lg-0 ml-3" id="navbarCollapse">
            <ul class="navbar-nav">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Product</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Shop</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">About</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Events</a>
                </li>
            </ul>
            <ul class="navbar-nav">
                <li class="nav-item">
                    <a class="nav-link pr-3" href="#"><i class="fa fa-facebook"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link pr-3" href="#"><i class="fa fa-instagram"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link pr-3" href="#"><i class="fa fa-twitter"></i></a>
                </li>
            </ul>
        </div>
    </div>
</nav>

Answer 1

您可以使用flex-column flexbox 实用程序类将 2 个导航垂直堆叠在图标旁边。这会将flex-direction: column 设置在navbar-collapse div 上，以便它的子元素垂直堆叠。

<nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse">
    <div class="container">
        <button class="navbar-toggler navbar-toggler-right align-self-center mt-3" type="button" data-toggle="collapse" data-target="#navbarCollapse">
            <span class="navbar-toggler-icon"></span>
        </button>
        <h1 class="py-2 ml-lg-2 mx-3"><a href="#"><i class="fa fa-envelope-o fa-lg mt-2" aria-hidden="true"></i></a></h1>
        <div class="collapse navbar-collapse flex-column ml-lg-0 ml-3" id="navbarCollapse">
            <ul class="navbar-nav">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Product</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Shop</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">About</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Events</a>
                </li>
            </ul>
            <ul class="navbar-nav flex-row mb-2">
                <li class="nav-item">
                    <a class="nav-link py-1 pr-3" href="#"><i class="fa fa-facebook"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link py-1 pr-3" href="#"><i class="fa fa-instagram"></i></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link py-1 pr-3" href="#"><i class="fa fa-twitter"></i></a>
                </li>
            </ul>
        </div>
    </div>
</nav>

Answer 2

对我来说，“2 行右对齐的变体”没有右对齐 Safari 中的行。我将无序列表放在一个带有flex-column 和ml-auto 类的新div 中。

<nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse">
    <div class="container">
      <button class="navbar-toggler navbar-toggler-right align-self-center mt-3" type="button" data-toggle="collapse" data-target="#navbarCollapse"> <span class="navbar-toggler-icon"></span> </button>
      <h1 class="py-2 ml-lg-2 mx-3"><a href="#"><i class="fa fa-envelope-open-o fa-lg" aria-hidden="true"></i></a></h1>
      <div class="collapse navbar-collapse ml-lg-0 ml-3" id="navbarCollapse">
        <div class="flex-column ml-auto">
          <ul class="navbar-nav">
            <li class="nav-item active"> <a class="nav-link" href="#">Home</a> </li>
            <li class="nav-item"> <a class="nav-link" href="#">Product</a> </li>
            <li class="nav-item"> <a class="nav-link" href="#">Shop</a> </li>
            <li class="nav-item"> <a class="nav-link" href="#">About</a> </li>
            <li class="nav-item"> <a class="nav-link" href="#">Events</a> </li>
          </ul>
          <ul class="navbar-nav">
            <li class="nav-item"> <a class="nav-link pr-3" href="#"><i class="fa fa-facebook"></i></a> </li>
            <li class="nav-item"> <a class="nav-link pr-3" href="#"><i class="fa fa-instagram"></i></a> </li>
            <li class="nav-item"> <a class="nav-link pr-3" href="#"><i class="fa fa-twitter"></i></a> </li>
          </ul>
        </div>
      </div>
    </div>
  </nav>
