• Faceted search for complex product catalogs.

4. Design Navigation Schemes

• Primary navigation: topbar or hamburger menu.
• Secondary navigation: sidebars, footers, or breadcrumbs.
• Micronavigation: custom next/previous links.

5. Prototype & Test InContext

Utilize user testing, card sorting, and A/B experiments to validate the IA before full implementation.
