What could be causing my <UL> to not properly expand around the <LI> items inside of it?

I am currently working with WordPress and have created a menu using a list structure.

Here is an example of how it looks:

<ul>
    <li>Home</li>
    <li>About</li>
    <li>ParentItem
        <ul> <--- The height does not adjust to fit its children
            <li>ChildMenuItem 1</li>
            <li>ChildMenuItem 2</li>
        </ul>
    </li>
    <li>Services</li>
</ul>

The issue I am facing is that the ParentItem does not expand to cover all its children with its background and border. I have tried various solutions but the only way I can get it to cover is by setting a fixed height, which is not ideal.

Answer №1

To fix the size of your list, adjust the height property for the ul element from 100% to auto:

height: auto;

If you set the height of your ul to 100%, it will inherit the height of its parent container. This does not mean it will fill up all available space or add up the heights of its child elements. In this case, if the parent has a height of 33px, then that's what the ul will also be limited to.

Answer №2

This particular guideline states that:

.menu-primary-container ul li ul {
    height: 100%;
    /* ... */
}

It is required to eliminate the height property.

Furthermore, you should change the selector from:

.menu-primary-container ul

to:

.menu-primary-container > ul

This adjustment ensures that only the first ul element is targeted, and not all of its descendants.

Answer №3

The reason for this issue is that your list items (<li>) are floated left, causing them not to contribute to the shape of the parent element.

To resolve this, try removing the float property and adding clear:both to the nested list items (<li>). This should correct the layout problem.
