我创建了一个固定位置下拉菜单,但是当我选择一个下拉内容时,整个菜单栏都会折叠。请参阅附图。
如何创建正确的位置固定下拉菜单,其中下拉内容不会影响菜单栏?
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #003746;
position: fixed;
top: 0;
}
li {
float: left;
}
li a,
.dropbtn {
display: inline-block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
border-radius: 42px;
}
li a:hover,
.dropdown:hover .dropbtn {
background-color: green;
border-radius: 42px;
}
li.dropdown {
display: inline-block;
color: white
}
.dropdown-content {
display: none;
position: static;
background-color: #003746;
min-width: 16px;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
z-index: 1;
}
.dropdown-content a {
color: white;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
}
.dropdown-content a:hover {
background-color: green
}
.dropdown:hover .dropdown-content {
display: block;
}

<ul>
<li><img class="center" width="80" height="50" title="Example"></li>
<li class="dropdown">
<a class="dropbtn">AAA</a>
<div class="dropdown-content">
<a>AAA - AAA</a>
<a>AAA1 - AAA1</a>
</div>
</li>
<li class="dropdown">
<a class="dropbtn">BBB</a>
<div class="dropdown-content">
<a>BBB - BBB</a>
<a>BBB1 - BBB1</a>
</div>
</li>
</ul>

答案 0 :(得分:0)
您必须在下拉内容类上设置position: absolute;
。然后它会工作。 position: static;
是任何元素的初始位置。
哦,从 ul 元素中删除overflow: hidden;
。如果你保留这个财产,你基本上是在说。 &#34;任何从我的容器中出来的东西都隐藏起来!&#34;。
如果您保留该属性,下拉内容菜单将设置为display: block;
但不可见,因为它被其父元素隐藏(<ul>
元素)。
