3.2.1Definition & Anatomy
A mega menu is a large, multi-column dropdown panel that surfaces an entire section's structure at once, rather than nesting it behind sequential sub-menus.
3.2.2Common Mistakes
- Using a mega menu for a site that doesn't actually have enough depth to justify it, adding visual noise.
- No clear grouping/headers within the panel, turning it into an unsorted link dump.
- Poor keyboard and touch support, common since mega menus are often built hover-only.
3.2.3Best Practices
- Group links under clear category headers, mirroring the site's actual information architecture.
- Support click-to-open on touch devices, not hover-only interaction.
ExampleLarge e-commerce sites use mega menus to expose entire category trees (department → subcategory → type) in one panel instead of forcing multiple sequential clicks.
