Question

我想做一个这样的菜单http://bootsnipp.com/snippets/featured/multi-level-dropdown-menu-bs3，它必须是多级菜单，但我想只用点击打开菜单，也可以打开多级菜单，而不是鼠标悬停。此外，如果菜单打开并单击正文将关闭所有菜单。有人有任何想法吗？

提前致谢。

HTML

Map<String,Integer> newMap = 
    s.entrySet().stream()
                .collect(Collectors.toMap(Map.Entry::getValue,Map.Entry::getKey));

CSS

string cubeinline = "12345123451234X1234512345";
List<string> cube = new List<string>(){ "12345",
                                    "12345",
                                    "1234X",
                                    "12345",
                                    "12345"};
bool isEqual = cubeinline == string.Concat(cube);

JS

<div class="container">
    <div class="row">
        <div class="dropdown">
            <a id="dLabel" role="button" data-toggle="dropdown" class="btn btn-primary" data-target="#" href="/page.html">
                Dropdown <span class="caret"></span>
            </a>
            <ul class="dropdown-menu multi-level" role="menu" aria-labelledby="dropdownMenu">

              <li><a href="#">Some other action</a></li>
              <li class="divider"></li>
              <li class="dropdown-submenu">
                <a tabindex="-1" href="#">Hover me for more options</a>

                  <li><a href="#">Second level</a></li>
                </ul>
              </li>

Answer 1

解决方案是：

JS

$(function(){
    $(".dropdown-submenu").on("click",function(e){
    var current=$(this).find(".dropdown-menu").first();
    console.log(current);
        current.toggle();
        e.stopPropagation();
    });


 $(document).click(function(){
   $(".dropdown-menu").hide('slow'); 
});


});

可点击的多级菜单
