A mega menu is a type of navigation menu that displays a large number of options in a visually appealing and organized manner. Unlike traditional drop-down menus, a mega menu typically expands horizontally or vertically to showcase multiple levels of navigation, allowing users to easily access a wide range of content or features within a website or application. This type of menu is often used on complex or content-heavy websites, providing users with a comprehensive and efficient way to navigate and find what they are looking for. With its spacious layout and customizable design, a mega menu offers a user-friendly and intuitive browsing experience, making it a popular choice for modern websites.
