A navigation menu is a user interface element that helps visitors find their way around a website or application. It typically appears at the top or side of a page and contains links to important sections, such as Home, About Us, Services, and Contact. This organized layout allows users to quickly access the information they need. Navigation menus can be designed in various styles, including horizontal, vertical, or dropdown formats. They enhance user experience by providing a clear structure, making it easier for users to explore content without getting lost. Effective navigation is crucial for retaining visitors and improving site usability.
