OpenCart Menu Menu also knows as OpenCart mega header is an extended version of the website default menu where the layout of the menu is organized in a more effective way for customers to navigate among a large group of menus.

Often known as opencart mega menu extension, this Mega Menu is a multi-column version of the default menus normally available on any website. The majority of the website uses a mega menu module to get ride of a traditional simple look. This makes stand it among the best opencart extensions.

However, the opencart vertical mega menu allows you to add multi-column drop-down menus to your navigation also with media items such as images and videos.

It can also transform your default menu bar to a wide array of multi-columns that brings in elegance and beauty to your OpenCart store. Mega Menu can show a lot of information like categories, products, information page. Offers, and discount items and a number of categories and sub-categories i.e multi-level menu related to your products on the store.

A customer can view a lot of information on the mega menu such as sale items, categories, subcategories, videos, banners of discount, latest products, and more.
All these things can place in three columns, this makes it responsive in mobile and tablets.

One Regular menu which shows text links while hovering on menus. The second one is Mega Menu which shows Text and Images or Videos as well on Menus.

Which makes Mega Menu different than regular menus. We can show more than text on menus. default Product image can be show or Category image can be shown. Also, they support multi-level menus structure, unlike regular Menu.
