Struggling with displaying a CSS dropdown menu below its parent element?

I need help with my menu structure.

<nav id="nav">
 <ul>
  <li>Home</li>
  <li>Menu1
   <ul>
    <li>Sub1</li>
    <li>Sub2</li>
   </ul>
  </li>
  <li>Menu2
   <ul>
    <li>Sub1</li>
    <li>Sub2</li>
   </ul>
  </li>
 </ul>
</nav>

Here is the CSS I am using for this menu:

#nav ul li {
    display: inline;
}
#nav ul ul {
    display: none;  
}
#nav ul li:hover > ul {
    display: block;
    position: absolute;
}
#nav ul ul li {
    display: block; 
}

Although the sub-menu items drop down correctly, they appear under the wrong parent list item (Home).

What adjustments can be made to ensure the sub-menus align correctly with their respective parent list items?

Answer №1

Check out this solution in action with the following fiddle link: http://jsbin.com/akazev/2/edit

Take a look at the updated CSS below:

nav ul li {
    display:  block;
    float: left;
}
nav ul ul {
    display: none;  
}
nav ul li:hover > ul {
    display: block;
    position: absolute;
    margin-left: -30px;
}
nav ul ul li {
    display: block; 
    float: none;
}

Rather than displaying your top-level links as inline, consider using inline-block or float. This adjustment resolved the issue with the navigation bar. If you opt for float (as demonstrated), remember to reset the deeper level links to float: none. Additionally, ensure you set a margin-left property for the absolutely positioned ul elements.

PS: Do you think having <nav id="nav"> is somewhat unnecessary?

<html>
<head>
<style type="text/css>
#navigation ul li {
    float:left;
}
#navigation ul ul {
    display: none;

Give this a try!

Your HTML Code:

<div id="navigationMenu">
        <ul>
            <li>Home</li>

            <li>Menu1
                <ul>
                    <li>Subcategory1</li>
                    <li>Subcategory2</li>
                </ul>
            </li>
            <li>Menu2
                <ul>
                    <li>Subcategory1</li>
                    <li>Subcategory2</li>
                </ul>
            </li>
        </ul>
    </div>

CSS Styles:

#navigationMenu{
    margin:0;
    padding:0;
}
#navigationMenu ul{
    margin:0;
    padding:0;
    line-height:30px;
}
#navigationMenu li{
    margin:0;
    padding:5px;
    list-style:none;
    float:left;
    position:relative;
}
#navigationMenu ul ul{
    position:absolute;
    visibility:hidden;
} 
#navigationMenu ul li:hover ul{
    right: auto;
    left: 0;
    visibility:visible
}
