Sometimes HTML version of the theme doesn’t come with dropdown menu in menu bar, here is a simple way to add dropdown menu to your HTML:

Add the following HTML to your markup

<nav>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">WordPress</a>

<!-- First Tier Drop Down -->
<ul>
<li><a href="#">Themes</a></li>
<li><a href="#">Plugins</a></li>
<li><a href="#">Tutorials</a></li>
</ul>

</li>
<li><a href="#">Graphic Design</a></li>
<li><a href="#">Inspiration</a></li>
<li><a href="#">Contact</a></li>
<li><a href="#">About</a></li>
</ul>
</nav>h

Note that dropdown is simply adding <ul> into <li> of the first level.

After that, here is the explanation of the following CSS:

  • Hide ul ul in menu (which is dropdown level)
  • Show hidden dropdown menu in ul li:hover ul
  • Adjust the dropdown menu width with ul ul li
  • Position 2nd+ tier dropdown with ul ul ul (Untested)

You can see my code below. Feel free to adapt to your own menu.

/* Normal Menu CSS */
#nav-wrapper ul {
float: none;
margin: 0 auto;
text-align: center;
}

#nav-wrapper ul li {
float: none;
display: inline-block;
text-align: center;
margin-right: 35px;
}

#nav-wrapper ul li a {
color: #404040;
font-size: 15px;
}

/* Dropdown Menu CSS */
#nav-wrapper ul ul {
display: none;
position: absolute;
top: 100%;
left: 0;
margin: 0;
padding: 0;
}

#nav-wrapper ul li {
position: relative;
}

#nav-wrapper ul li:hover > ul {
display: block;
}

#nav-wrapper ul ul li {
min-width: 170px;
background: #fff;
margin-right: 0;
padding: 10px 15px;
display: block;
text-align: left;
}

#nav-wrapper ul ul li:last-child {
padding-bottom: 20px;
}

#nav-wrapper ul ul ul {
position: absolute;
top:0;
left:100%;
}
