自举下拉菜单在移动设备上不工作
自举下拉菜单在移动设备上不工作
提问于 2019-06-10 07:09:02
我在我的网站上添加了一个下拉列表，但是当导航条崩溃时，它在移动设备上不能正常工作。当我点击下拉时，它关闭肚脐，而不是显示在下拉列表下的项目。
.dropdown-submenu {
position: relative;
}
.dropdown-submenu .dropdown-menu {
top: 0;
left: 100%;
margin-top: -1px;

这就是你要找的吗？带子菜单的Navbar
(function($) {
$(document).ready(function() {
$('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
event.preventDefault();
event.stopPropagation();
$(this).parent().siblings().removeClass('open');
$(this).parent().toggleClass('open');
});
});
})(jQuery);.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>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: #555;
}
.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;
