引导程序的新手.这是基于Bootstrap示例的代码.现在会显示下拉列表，但您无法单击下拉列表本身.我希望能够使所有父级导航链接正常工作.与此网站相似: https://eastcfashion.com/

New to bootstrap. Here's the code based on the Bootstrap example. Right now the dropdown shows up but you're not able to click on the dropdown itself. I want to be able to make all the parent nav links work. Similar to this website: https://eastcfashion.com/

例如，在其中单击:男士系列将您带到该地区的所有集合.但是，在下拉菜单中，您仅可以进行特定的项目.

Where clicking on for example: men's collection brings you to all the collection for that area. But the dropdown menu, you're able to just go on specific items.

我正在尝试以一种主要的父导航表示Projects的方式来实现它.然后项目的下拉菜单将显示每个项目的特定页面，例如项目1，项目2等.但是，单击项目"会将您带到一个页面，其中项目1，项目2和项目集合将显示为一个组.而不是单独.

I'm trying to implement it in a way that the main parent nav would say Projects. and the dropdown menu for projects would show specific pages for each project like project 1, project 2, etc. But clicking on Projects would take you to a page where project 1, project 2, and the collection of projects would be showing as a group and not individually.

推荐答案

jQuery(function($) {
  if ($(window).width() > 769) {
    $('.navbar .dropdown').hover(function() {
      $(this).find('.dropdown-menu').first().stop(true, true).delay(250).slideDown();

    }, function() {
      $(this).find('.dropdown-menu').first().stop(true, true).delay(100).slideUp();

    });

    $('.navbar .dropdown > a').click(function() {
      location.href = this.href;
    });

  }
});

@media only screen and (min-width:769px) {
  .dropdown:hover .dropdown-menu {
    display: block;
  }
  .dropdown-submenu {
    position: relative !important;
  }
  .dropdown-submenu>.dropdown-menu {
    top: 0 !important;
    left: 100% !important;
    margin-top: -6px !important;
    margin-left: -1px !important;
    border-radius: 0 !important;
  }
  .dropdown-submenu:hover>.dropdown-menu {
    display: block !important;
  }
  .dropdown-submenu>a:after {
    display: block;
    content: "\f105";
    font-family: 'FontAwesome';
    margin-top: -18px;
    right: 15px;
    position: absolute;
    font-weight: 300;
  }
}
