Jakob Nielsen: "Mega menus show everything at a glance, so users can see rather than try to remember"

Quote (Jakob Nielsen, NN/g):

"Mega menus show everything at a glance, so users can see rather than try to remember."

Confidence: Verified. Foundational NN/g mega-menu guidance, still cited current 2023-2026.

Implication: Regular dropdowns hide most options behind a hover-trigger. Mega menus surface the IA — users see the breadth of the site at the navigation level. For multi-vertical service businesses where the matrix is the value proposition, the mega menu is the right surface. See NN/g mega-menu hover protocol: wait 0.5s before showing, then display within 0.1s for the timing rules and NN/g: "On large screens, don't cover the entire screen when megamenus are open" (Apr 30 2023) for the size constraint.
