响应式导航栏，带子菜单

Question

我需要创建一个包含项目和子项目的响应式导航栏菜单。我已尝试使用bootstrap，但添加子菜单会变得不方便。

有任何工具，框架，代码或插件可以帮助我吗？

我的网站是由AngularJS制作的。

带子菜单的Bootstrap Navbar

＆＃13;

＆＃13;

$(document).ready(function() {
  $('.navbar a.dropdown-toggle').on('click', function(e) {
    var $el = $(this);
    var $parent = $(this).offsetParent(".dropdown-menu");
    $(this).parent("li").toggleClass('open');

    if (!$parent.parent().hasClass('nav')) {
      $el.next().css({
        "top": $el[0].offsetTop,
        "left": $parent.outerWidth() - 4
      });
    }

    $('.nav li.open').not($(this).parents("li")).removeClass("open");

    return false;
  });
});

＆＃13;

@media (min-width: 767px) {
  .navbar-nav .dropdown-menu .caret {
    transform: rotate(-90deg);
  }
}

Answer 2

你可以试试这个：

<nav class="navbar navbar-inverse">
  <div class="container-fluid">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>                        
      </button>
      <div class="col-md-12 clearfix">
      <div class="row"> 
      <a class="navbar-brand" href="#">WebSiteName</a>
      </div>
      </div>
    </div>

    <div class="col-md-12 clearfix"> 
    <div class="row">
    <div class="collapse navbar-collapse" id="myNavbar">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home</a></li>
        <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" href="#">Page 1 <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Page 1-1</a></li>
            <li><a href="#">Page 1-2</a></li>
            <li><a href="#">Page 1-3</a></li>
          </ul>
        </li>
        <li><a href="#">Page 2</a></li>
        <li><a href="#">Page 3</a></li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li><a href="#"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
        <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
      </ul>
    </div>
    </div>
    </div>

  </div>

它看起来如下：
