Bootstrap 3 - 悬停在桌面上的菜单，但在最小化时点击打开（移动导航）

Question

使用 Bootstrap 3。

我正在尝试使用悬停在桌面上保持网站导航正常工作，但在使用移动导航时，我希望导航在点击时打开。我似乎无法让我的选择与我所拥有的一起工作。我对 CSS 没有很好的掌握，所以我可能会用一些小东西……或大东西来搞砸它……

现在该网站在桌面版上运行良好，点击时导航打开，然后悬停打开剩余的子链接。问题是当我将页面宽度减小到移动版本时，导航无法按我的意愿工作。我得到的是悬停时打开的导航，但我希望每个链接仅在点击时打开。

我创建了一个 bootply 作为示例：http://www.bootply.com/tjL1FPgPT4

和 CSS：

    /*custom for submenu here*/


.dropdown-submenu {
    position:relative;
}
.dropdown-submenu>.dropdown-menu {
    top:0;
    left:100%;
    margin-top:-6px;
    margin-left:-1px;
    -webkit-border-radius:0 6px 6px 6px;
    -moz-border-radius:0 6px 6px 6px;
    border-radius:0 6px 6px 6px;
}

.dropdown-submenu:hover>.dropdown-menu {
    display:block;
}

.dropdown-submenu>a:after {
    display:block;
    content:" ";
    float:right;
    width:0;
    height:0;
    border-color:transparent;
    border-style:solid;
    border-width:5px 0 5px 5px;
    border-left-color:#cccccc;
    margin-top:5px;
    margin-right:-10px;
}
.dropdown-submenu:hover>a:after {
    border-left-color:#ffffff;
}
.dropdown-submenu.pull-left {
    float:none;
}
.dropdown-submenu.pull-left>.dropdown-menu {
    left:-100%;
    margin-left:10px;
    -webkit-border-radius:6px 0 6px 6px;
    -moz-border-radius:6px 0 6px 6px;
    border-radius:6px 0 6px 6px;
}

 @media only screen and (max-width:767px){
    .dropdown-submenu{
        display: block;
        position: static;
        background-color:transparent;
        border:0 none;
        box-shadow:none;
        margin-top:0;

    }

    .navbar-nav .dropdown-menu > li > a, 
    .navbar-nav .dropdown-menu .dropdown-header {
        padding:5px 15px 5px 25px;

    }

    .navbar-nav .dropdown-menu > li > a{
        line-height:20px;
    }

    .navbar-default .navbar-nav .dropdown-menu > li > a{
        color:#777;
    }

  .navbar-nav .dropdown-menu .dropdown-submenu > a{
        display:block;
        margin-top: 0;
  }
}

Answer 1

把你的css改成这个

 @media only screen and (min-width:768px){
  .dropdown-submenu:hover>.dropdown-menu {
    display:block;
  }
}

也将此脚本添加到页面。

$(document).ready(function(){
  $('.dropdown-submenu a').on("click", function(e){
    $(this).next('ul').toggle();
    e.stopPropagation();
    e.preventDefault();
  });
});
