Question

我正在使用定制的CSS和HTML设计网站。我不能在导航栏菜单中创建子子菜单。就像我希望在主菜单中将“服务”作为选项，然后将“打印介质”作为“服务”的子菜单，然后将“ Option1”，“ Option2”，“ Option3”，“ Option4”作为子菜单“印刷媒体”

结构应如下：

Services->PrintMedia->Option1;
                    ->Option2;
                    ->Option3;
                    ->Option4;
Services->ElectronicMedia->Option5;
                         ->Option6;
                         ->Option7;
                         ->Option7;

，我想让它响应。

我尝试了许多可能的事情，但是由于我的自定义CSS，我无法按原样实现代码。

 <div class="navbar navbar-inverse" role="banner">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>

CSS

ul.sub-menu {

  list-style: none;
  padding: 0;
  margin: 0;
}

#header .navbar-nav li ul.sub-menu li a{
  color: #818285;
  padding: 5px 0;
  font-size: 13px;
  display: block;
  text-transform: capitalize;

  background: #00aeef;

  position: relative;

根据我的理解，您正在寻找嵌套子菜单。如果是，以下是相同的解决方案。来源Skelly Codeply

exit()

$('.dropdown-menu a.dropdown-toggle').on('click', function(e) {
  if (!$(this).next().hasClass('show')) {
    $(this).parents('.dropdown-menu').first().find('.show').removeClass("show");
  }
  var $subMenu = $(this).next(".dropdown-menu");
  $subMenu.toggleClass('show');
  $(this).parents('li.nav-item.dropdown.show').on('hidden.bs.dropdown', function(e) {
    $('.dropdown-submenu .show').removeClass("show");
  });
  return false;
});

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu>.dropdown-menu {
  top: 0;
  left: -10rem;
  /* 10rem is the min-width of dropdown-menu */
  margin-top: -6px;
}


/* rotate caret on hover */

.dropdown-menu>li>a:hover:after {
  text-decoration: underline;
  transform: rotate(-90deg);
}

如何在当前代码中获取子菜单？
