When to use it

Use a mega menu when your navigation tree has 20+ leaf nodes spread across 3–6 top-level categories. It collapses depth into a single interaction — hover or click — and lets users scan everything without bouncing between pages.

Structure

Anchor the trigger in the primary nav bar. On activation, render a full-width panel with a multi-column grid. Each column gets a category label and a short list of links. Keep link labels under 30 characters. Add a featured card in the rightmost column for promotions or recent items.

Motion & timing

Open on hover with a 150ms delay to avoid accidental triggers. Close on mouse-leave with a 100ms grace period so users can cross gaps between the trigger and the panel. Use opacity + translateY (4px) for the transition — no scale transforms.

Accessibility

The trigger must be a button with aria-expanded. The panel gets role="region" and aria-label. Arrow keys navigate columns; Escape closes. Focus trap is optional but recommended for click-activated variants.
