Sticky nav

Shrink, hide, and change colour on scroll — all config-driven.

🧩

Mega menus

Full-width layouts with columns, images, badges, and custom content.

From config to live nav in seconds

Define your menu structure as a simple JSON object, pass it to the engine, and it handles the rest.

1. Define your structure

Items, dropdowns, mega panels — all expressed as a clean JSON config object.

2. Apply your tokens

Map GenCSS custom properties to menu slots — fonts, colours, spacing, radius.

3. Export & embed

Copy the generated config, drop it into your project alongside menu-engine.js.

4. Ship it

Your nav works in any browser, with any CMS, without touching a build pipeline.

Loved by designers and developers

Built for the Fewd Studio ecosystem — where great design meets clean code.

"Dropped it in, mapped my GenCSS tokens, and had a fully branded sticky mega nav running in under ten minutes. Remarkable."
Sarah K.Lead Developer, Studio Nine
"The visual builder saves me from having to hand-edit JSON configs. The scroll colour override is exactly what I needed for a transparent header."
Marcus T.Freelance Web Designer
"Finally, a nav component that doesn't fight with my design system. The token mapping means it inherits all my brand colours automatically."
Priya M.Design Systems Lead, Cascade Co.
"Clean API, great accessibility defaults, and it just works. This is how components should be built."
Daniel R.Frontend Engineer, Bloom Labs
