8 CSS & JavaScript Snippets for Creating Mega Menus


When it comes to website navigation, the old rule of thumb is that content should be no more than a click or two away. It’s all about ensuring users can find what they need without having to jump through hoops.

But the more content you have, the more difficult it becomes to organize navigation. Long drop-down menus or those with multiple nested levels can be a pain to use. They’re more likely to send potential customers to another site than entice them to explore yours.

That’s where a well-designed mega menu can make a difference. They provide a way to neatly organize menu items and allow users to find exactly what they’re looking for.

They’re also incredibly flexible. In addition to text, they can house anything from images to a search UI – all using standard CSS layout techniques.

Today, we’ll share 8 CSS and JavaScript snippets for building mega menus. You’ll find everything from simple, text-based navigation to richly-styled UIs. Here we go!
