如何在 Bootstrap 中创建具有多列的导航栏下拉菜单？

Question

我想知道如何使用 Bootstrap 创建一个包含多个垂直列的导航栏下拉菜单。就我而言，我的链接是分类的，我希望每个类别类型都有一列。

这是一个带有多列的 Bootstrap 导航栏下拉示例：

<div class="collapse navbar-collapse" id="myNavbar">
    <ul class="nav navbar-nav dropdown">
        <li class="active"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Online Retailers <span class="caret"></span></a>
            <ul class="dropdown-menu">
                <li class="dropdown-header "><h4> Get 100% off on your first order. </h4>
                    <li><a href="#">Domino's Pizza</a></li>
                    <li><a href="#">Food Panda</a></li>
                    <li><a href="#">Mc Donalds</a></li>
                </li>
                <li><a href="#">Page 1-2</a></li>
                <li><a href="#">Page 1-3</a></li>
            </ul>
        </li>
        <li><a class="dropdown-toggle" data-toggle="dropdown" href="#">Hey Foodies <span class="caret"></span></a>
            <ul class="dropdown-menu">
                <li class="dropdown-header "><h4> Get 100% off on your first order. </h4></li>
                <li class="divider"></li>
                <li><a href="#">Domino's Pizza</a></li>
                <li><a href="#">Food Panda</a></li>
                <li><a href="#">Mc Donalds</a></li>
                <li><a href="#">Pizza Hut</a></li>
                <li><a href="#">Tasty Khana</a></li>
                <li><a href="#">Tiny Owl</a></li>
                <li><a href="#">KFC</a></li>
            </ul>
        </li>

这个插件可能会有所帮助：Yamm3! MegMenu。请参阅示例片段和 Bootsnipp 上的另一个示例。

  $(function() {
    window.prettyPrint && prettyPrint()
    $(document).on('click', '.yamm .dropdown-menu', function(e) {
      e.stopPropagation()
    })
  })
