Measured entry

shadcn-button-group

buttonunclassified

A source-copied React primitive for visually joining buttons, labels, and separators in horizontal or vertical groups. It ships as Tailwind-styled component code and relies on the shadcn class-merging helper, class-variance-authority, Radix Slot, and the companion Separator primitive.

Verdict

A dependable layout primitive when the surrounding controls already own their state and semantics. It built and mounted cleanly, stayed contained across the tested layouts, and produced no automated accessibility findings, but it is not a full interaction pattern by itself.

Use it if

  • You need a compact toolbar or view switcher whose adjacent controls share borders and corner treatment.
  • Your React app already uses Tailwind and shadcn conventions, including the shared class-merging helper.
  • You want horizontal and vertical grouping while retaining control over the actual buttons and their behavior.

Skip it if

  • You need a complete segmented-control widget with selection state and keyboard behavior built in.
  • Your design system avoids Tailwind utility classes or source-copied components.
  • You want a dependency-free wrapper and do not already carry the Radix and variant-class utilities.

Providerno provider required in the harness

In a non-shadcn project, add Tailwind, class-variance-authority, Radix UI, clsx, and tailwind-merge; provide a compatible cn helper and copy or replace the Separator primitive. Also map the source import aliases to your project structure.
