jquery - 可点击的多级菜单

Question

我想做一个像这样的菜单http://bootsnipp.com/snippets/featured/multi-level-dropdown-menu-bs3 ，它必须是多级菜单，但我只想通过点击打开菜单，还有多级元素，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。有人知道吗？

提前致谢。

Answer 1

解决方法是:

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'); 
});


});
