Measured entry

shadcn-item

cardunclassified

A composable React item-row family for media, text, actions, headers, footers, groups, and separators. It ships as shadcn registry source copied into your app, styled with Tailwind classes and variants, and relies on Radix Slot, the shadcn Separator, class-variance-authority, and a cn utility backed by clsx and tailwind-merge.

What the harness recorded

BARE BUILD

error during build:
[vite]: Rollup failed to resolve import "class-variance-authority" from "<sandbox>re-837c88b3dcec/src/cut/components/ui/item.tsx".

Verdict

A practical set of flexible row primitives that builds and mounts cleanly, but it is not ready to copy unchanged. Fix the group's list semantics and replace the demo's fixed width for narrow layouts. Best suited to teams already comfortable maintaining shadcn source.

Use it if

  • You need consistent rows for settings, project lists, notifications, or compact resource cards.
  • Your team wants source-owned primitives that can render as links or custom child elements.
  • Your interface already uses Tailwind and shadcn design tokens.

Skip it if

  • You need an accessible list without adding list-item semantics to each row.
  • You want a packaged component with styles isolated from your Tailwind theme.
  • You plan to keep the demo's fixed width on narrow screens, where it overflows.
  • You need richer card behavior such as selection, disclosure, or built-in loading states.

Providerno provider required in the harness

In a non-shadcn project, add React, Tailwind, radix-ui, class-variance-authority, clsx, and tailwind-merge. Provide the cn helper and Separator component, configure the import aliases, and define the muted, accent, border, ring, and foreground theme tokens used by the classes.
