Ensure the right size for dropdown menus

When designing menus, particularly mega menus for large screens, it’s important to strike a balance between ensuring visibility and not dominating the screen. Menus should help improve the user experience by clearly displaying navigation options without obscuring the main content. If a menu is too large, it can cover up underlying content, causing confusion or misleading users into thinking they’ve navigated to a different page.

This principle holds less on mobile devices, where screen real estate is limited, and full-screen menus are often necessary to provide adequate touch targets. However, on desktops, menus that cover the full screen can disrupt the user experience by temporarily hiding the content users are interacting with.
