What could be causing the dropdown menu to not display below its container when the overflow:hidden CSS property is applied to the container element

Question

What could be causing the dropdown menu to not display below its container when the overflow:hidden CSS property is applied to the container element

One issue I'm facing is that the dropdown submenu of my navigation menu does not extend beyond its container element when displayed. My code includes main menu items (HOME, ABOUT, SERVICES, PRODUCTS, and CONTACT) along with submenu items (A, B, C, D, E) for each main menu item. However, the submenu items only appear below their respective main menu items when I increase the padding of the main menu items to ensure the background covers the submenu items. Otherwise, they are not visible. Here's a snippet of my code:

.menu{
width: 100%;
background: #d80000;
float: left;
margin-bottom: 50px;
display: block;
overflow: hidden;
padding: 10px 10px;
}
.menu .mainmenu{
margin-left: -40px;
/*display: none;*/
}

... (CSS and HTML code included here)

The desired outcome is for the submenu to drop down and display below the corresponding main menu item as we hover over them. However, this functionality is not working properly in the current code.

Answer 1

Answer №1

The reason your submenu is not showing is because of the overflow: hidden; property in your styling for the .menu class.

To make the submenu visible, you need to delete that line from your CSS.

Consider using a different class to manage the float instead.

.clear { clear: both; }

After your last <li>, add:

<div class="clear"></div>

Answer №3

When an element is taller than its container and floated, it tends to overflow outside of the container. To fix this issue, you can use the following code snippet:

.clearfix::after {
  content: "";
  clear: both;
  display: table;
}

Your content contains multiple instances of <a href=#"> with a missing quote mark. It should be corrected to <a href="#"> instead.

Answer №5

Appreciate the responses. Below is the finalized code with all errors rectified from the previous version.

Key points to note:

Implemented display:flex instead of float left
Due to the removal of float, there is no need for a clearfix class which prevents the submenu from stacking upwards.
Removed overflow:hidden from the original code, as it was causing the drop-down menu to be hidden.

This updated answer corrects the erroneous code I previously shared.

.menu{
background: #d80000;
width: 100%;
padding:10px 10px;
}

.mainmenu{
list-style: none;
display: flex;
}

.mainmenu .heading{
margin-right: 2px;
}

.mainmenu .heading a{
text-decoration: none;
display: inline-block;
padding: 10px 20px;
color: #d80000;
background: #fff;
position: relative;
width: 80px;
text-align: center;
text-transform: uppercase;
}

.submenu{
list-style: none;
position: absolute;
display: none;
}
.heading a:hover{
background: #d80000;
color: #fff;
}

.heading:hover .submenu{
display: block;
margin-left: -40px;
}

.submenu .items a{
width: 80px;
text-align: center;
border-top: 1px solid #d80000;
}
