I'm trying to add a dropdown menu inside a navigation bar. I'm using the code provided by https://www.w3schools.com/css/css_dropdowns.asp, but when I try to fix the bar at the top of the page, the dropdown menu doesn't show anymore.
This is the code with a working dropdown menu:
<!DOCTYPE html>
<html lang="it">
<head>
<meta charset="UTF-8">
<style>
body {margin:0;}
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
li {
float: left;
}
li a, .dropbtn {
display: inline-block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
li a:hover, .dropdown:hover .dropbtn {
background-color: red;
}
li.dropdown {
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
}
.dropdown-content a:hover {background-color: #f1f1f1;}
.dropdown:hover .dropdown-content {
display: block;
}
</style>
</head>
<body>
<ul>
<li><a href="#home">Home</a></li>
<li><a href="#news">News</a></li>
<li class="dropdown">
<a href="#" class="dropbtn">Dropdown</a>
<div class="dropdown-content">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</li>
</ul>
<div style="margin:20px;">
<h3>Dropdown Menu inside a Navigation Bar</h3>
<p style="height:3000px;">This should be a simple responsive webpage with a fixed navbar and a dropdown menu.</p>
</div>
</body>
</html>
But if I add
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
position: fixed;
width: 100%;
top: 0;
}
...the dropdown menu disappears. What should I do? Thanks.
