MegaMenu replaces a scaffold with a trigger and a wide panel of grouped link columns. One level deep on purpose: a mega menu exists to show breadth flat so everything is one click away, and nesting inside the panel buries content behind hover-within-hover. Nav is the component for cascading submenus. The panel is anchored so the runtime clamp keeps it inside the viewport. Sidebar now composes Drawer for its off-canvas presentation instead of a hand-rolled backdrop, inheriting the focus trap and scroll lock from one place. Single items, labelled groups and branches nested to three levels, with vertical roving focus. Sidebar classes move to the BEM naming the rest of the library uses, which is a breaking change; nesting via children still works, since that is what shipped in 0.8.5.

WRNexus UI component showcase
The showcase is generated from packages/ui/component-reference.json. It stays
synchronized with the current component source rather than maintaining a second
hand-written catalog.
bun run --cwd examples/component-showcase dev
Open http://localhost:3000.
Detail-page coverage
Every current UI component receives a dedicated detail page with:
- an interactive server-rendered playground for every declared prop
- typed boolean, number, array, and object controls
- public component-tag syntax with single-quoted dynamic WRN expressions
- component-specific production use cases when a profile exists
- responsive fallback examples for every remaining component
- copyable
.wrnsource beside every live preview - complete props, slots, and explicitly declared public events
- live
event.detailoutput for interactive components - previous and next component navigation
The specialized profiles for new and recently repaired components live in:
scripts/showcase-profiles.mjs
Update that file to add product-quality examples or public enum options. Do not infer allowed prop values from implementation comparisons; unrestricted values such as icon classes, labels, IDs, and URLs must remain free-form inputs.
Generated files
The generator creates:
app/layouts/showcase.wrn
app/layouts/document.wrn
app/pages/*.wrn
app/pages/components/*.wrn
showcase-manifest.json
showcase-manifest.json records component, category, demo, prop, slot, and event
coverage and is used by the test suite. Do not hand-edit generated pages.
Validation
After changing UI components, metadata, profiles, the playground, or showcase styles, run:
bun run scripts/generate-ui-component-reference.mjs
bun run --cwd examples/component-showcase generate
bun run --cwd examples/component-showcase test
bun run --cwd examples/component-showcase build
The complete local check is:
bun run --cwd examples/component-showcase check
Review representative component pages at mobile, tablet, and desktop widths and in light, dark, keyboard-only, and reduced-motion modes before publishing.
