使用下拉列表引导不可折叠的导航栏

Bootstrap non collapsable navbar with dropdowns

本文关键字：可折叠 导航 下拉列表      更新时间：2023-09-26

我正在尝试创建没有响应的导航栏，并且有一些下拉菜单

我能够通过下面的 css 使其无响应。但是，如果我单击移动设备导航栏中的下拉菜单，它就会搞砸。这里是引导 http://www.bootply.com/k9wnO3WaO4，尝试移动视图并点击todo重现此问题。

<style>
.navbar-collapse.collapse {
display: block!important;
}
.navbar-nav>li, .navbar-nav {
float: left !important;
}

.navbar-nav.navbar-right:last-child {
margin-right: -15px !important;
}
.navbar-right {
float: right!important;
}
</style>

示例下拉列表

<li class="dropdown"><a href="#" data-tad="l1" class="nottodo dropdown-toggle" data-toggle="dropdown">Todo <span class="label label-info">0</span>
                </a>
                    <ul class="dropdown-menu">
                        <li><a href="#"><span class="label label-warning">4:00 AM</span>Favourites Snippet</a></li>
                        <li><a href="#"><span class="label label-warning">4:30 AM</span>Email marketing</a></li>
                        <li><a href="#"><span class="label label-warning">5:00 AM</span>Subscriber focused email
                            design</a></li>
                        <li class="divider"></li>
                        <li><a href="#" class="text-center">View All</a></li>
                    </ul>
                </li>

有一个媒体查询负责我认为您不喜欢的行为。

在 css 中，以下媒体查询：

@media (max-width: 767px) {
    .navbar-nav .open .dropdown-menu {
         background-color: transparent;
         border: 0 none;
         box-shadow: none;
         float: none;
         margin-top: 0;
         position: static;
         width: auto;
    }
...
}

只需像以下 css 一样覆盖样式：

.navbar-nav .open .dropdown-menu {
    background-color: #fff;
    border: 1px solid rgba(0, 0, 0, 0.15);
    border-radius: 4px;
    box-shadow: 0 6px 12px rgba(0, 0, 0, 0.176);
}

您可以在此处找到更新的Bootply。

在

下面的演示中，我不得不在背景颜色中添加!important。不知道为什么，因为在 Bootply 这不是必需的。

.navbar-collapse.collapse {
display: block!important;
}
.navbar-nav>li, .navbar-nav {
float: left !important;
}
.navbar-nav.navbar-right:last-child {
margin-right: -15px !important;
}
.navbar-right {
float: right!important;
}
.navbar-nav .open .dropdown-menu {
	background-color: #fff !important;
    border: 1px solid rgba(0, 0, 0, 0.15);
    border-radius: 4px;
    box-shadow: 0 6px 12px rgba(0, 0, 0, 0.176);
    position: static;
}
