Create A Mega Menu

Create a dropdown menu that appears when the user moves the mouse over an element inside a navigation bar.

Step 1) Add HTML:

Example

<div class=”navbar”>
  <a href=”#home”>Home</a>
  <a href=”#news”>News</a>
  <div class=”dropdown”>
    <button class=”dropbtn”>Dropdown
      <i class=”fa fa-caret-down”></i>
    </button>
    <div class=”dropdown-content”>
      <div class=”header”>
        <h2>Mega Menu</h2>
      </div>
      <div class=”row”>
        <div class=”column”>
          <h3>Category 1</h3>
          <a href=”#”>Link 1</a>
          <a href=”#”>Link 2</a>
          <a href=”#”>Link 3</a>
        </div>
        <div class=”column”>
          <h3>Category 2</h3>
          <a href=”#”>Link 1</a>
          <a href=”#”>Link 2</a>
          <a href=”#”>Link 3</a>
        </div>
        <div class=”column”>
          <h3>Category 3</h3>
          <a href=”#”>Link 1</a>
          <a href=”#”>Link 2</a>
          <a href=”#”>Link 3</a>
        </div>
      </div>
    </div>
  </div>
</div>

Example Explained

Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element.

Use a container element (like <div>) to create the dropdown menu and add a grid (columns) and add dropdown links inside the grid.

Wrap a <div> element around the button and the container element (<div> to position the dropdown menu correctly with CSS.

Step 2) Add CSS:

Example

<!DOCTYPE html>
<html>
<head>
<link rel=”stylesheet” href=”https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css”>
<style>
* {
box-sizing: border-box;
}

body {
margin: 0;
}

.navbar {
overflow: hidden;
background-color: #333;
font-family: Arial, Helvetica, sans-serif;
}

.navbar a {
float: left;
font-size: 16px;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}

.dropdown {
float: left;
overflow: hidden;
}

.dropdown .dropbtn {
font-size: 16px;
border: none;
outline: none;
color: white;
padding: 14px 16px;
background-color: inherit;
font: inherit;
margin: 0;
}

.navbar a:hover, .dropdown:hover .dropbtn {
background-color: red;
}

.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
width: 100%;
left: 0;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}

.dropdown-content .header {
background: red;
padding: 16px;
color: white;
}

.dropdown:hover .dropdown-content {
display: block;
}

/* Create three equal columns that floats next to each other */
.column {
float: left;
width: 33.33%;
padding: 10px;
background-color: #ccc;
height: 250px;
}

.column a {
float: none;
color: black;
padding: 16px;
text-decoration: none;
display: block;
text-align: left;
}

.column a:hover {
background-color: #ddd;
}

/* Clear floats after the columns */
.row:after {
content: “”;
display: table;
clear: both;
}
</style>
</head>
<body style=”background-color:white;”>

<div style=”padding:16px”>
<h3>Mega Menu (Full-width dropdown in navbar)</h3>
<p>Hover over the “Dropdown” link to see the mega menu.</p>
</div>

</body>
</html>

Example Explained

We have styled the navigation bar and the navbar links with a background-color, padding, etc.

We have styled the dropdown button with a background-color, padding, etc.

The .dropdown-content class holds the actual dropdown menu. It is hidden by default, and will be displayed on hover (see below). It is positioned to be visible right below the dropdown button, and the width is set to 100% to cover the whole screen.

Instead of using a border, we have used the box-shadow property to make the dropdown menu look like a “card”. We also use z-index to place the dropdown in front of other elements.

The :hover selector is used to show the dropdown menu when the user moves the mouse over the dropdown button.

The .column classes are used to create three columns that floats next to each other inside the dropdown menu (to show different categories).
