我想创建一个这样的下拉菜单:
但我不能水平居中顶部三角形和下拉菜单(基于li a),我遇到了一些:hover问题,因为下拉ul消失了.
我怎样才能做到这一点？
JSFiddle:
html {
text-align: center;
}
nav {
width: 100%;
height: auto;
background-color: #000;
}
ul li {
display: inline-block;
position: relative;
margin: 1em
}
ul ul {
display: none;
position: absolute;
background-color: #000;
top: 50px;
}
ul ul:after {
position: absolute;
left: 50%;
top: -8px;
width: 0;
height: 0;
content: '';
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-bottom: 20px solid #000000;
}
a { …我正在尝试使用Materialize在侧边栏中创建一个下拉菜单,但它不起作用.下拉列表的宽度与触发器的宽度不同,并且填充将锚点移动到列表项的底部.(代码与docs网站相同)
这是Codepen的问题:例子
谢谢您的帮助 :)
$(document).ready(function(){
// Sidebar
$(".button-collapse").sideNav({menuWidth: 320, activationWidth: 70, edge: 'left'});
// Dropdown
$('.dropdown-button').dropdown({
inDuration: 300,
outDuration: 225,
constrain_width: false, // Does not change width of dropdown to that of the activator
hover: false, // Activate on hover
gutter: 0, // Spacing from edge
belowOrigin: false // Displays dropdown below the button
}
);
});<div id="slide-out" class="side-nav full">
<ul>
<li><a href="#">First Link</span></a></li>
<li><a href="#">Second Link</span></a></li>
<!-- Dropdown Trigger -->
<li><a class='dropdown-button' href='#' data-activates='dropdown1'>Drop Me!</a></li>
