NOVA — Smart Mega Menu with Context Preview

NOVA is a responsive mega menu concept designed to transform complex navigation into a more visual and intuitive discovery experience. Hovering or focusing on a solution dynamically updates an adjacent preview with custom artwork, supporting copy, key benefits, and a contextual CTA. The component combines CSS Grid, custom properties, animated interface states, and lightweight JavaScript state management. Intent-based hover interactions ensure smooth pointer movement on desktop, while mobile uses a compact disclosure pattern. Keyboard navigation, focus management, reduced-motion support, security protections, and a fully functional no-JavaScript fallback make the experience polished, accessible, and resilient.
