Measured entry

reui-timeline

cardminimal-flat

A composable React timeline for vertical or horizontal sequences, shipped as shadcn registry source rather than a packaged widget. It provides wrappers for items, dates, titles, content, indicators, and separators, with active-state styling. It depends on React, the Radix Slot export, Tailwind utility classes and a local cn helper.

Verdict

A solid set of styling primitives for teams already inside the shadcn ecosystem, but it is not a finished card and the default export alone appears empty. It needs a shadcn-style setup to build and mount, and active-step changes must be driven from outside the component.

Use it if

  • You need a presentational history, status trail, or milestone sequence assembled from small primitives.
  • Your app already uses shadcn conventions, Tailwind theme tokens, and the local cn utility.
  • You want controlled or initial active-step styling and need both vertical and horizontal layouts.

Skip it if

  • You want a complete drop-in timeline with sample events or card content included.
  • You need built-in step interaction, keyboard behavior, or an exported hook for changing the active item.
  • Your styling stack cannot process its Tailwind data, group, arbitrary-value, and descendant variants.
  • You need semantic list markup without adapting the supplied div-based primitives.

In a non-shadcn project, add React and radix-ui, provide the aliased local cn class-merging helper, and configure Tailwind with the theme tokens and variant syntax used by the source. Copy the registry component into your source tree, preserve client-component handling where applicable, and compose TimelineItem children explicitly.
