Measured entry

shadcn-tabs

tabsunclassified

A client-side React tabs primitive shipped as copy-in TypeScript source, with horizontal and vertical layouts plus default and line treatments. It wraps Radix UI for tab behavior and relies on class-variance-authority, the shadcn cn utility, Tailwind utilities, and shadcn theme tokens for styling.

Verdict

A solid fit inside an existing shadcn codebase, with accessible behavior and useful layout variants. It does not mount as a bare component and needs a shadcn-style setup; narrow tab rows also need an explicit responsive overflow strategy.

Use it if

  • You already use shadcn conventions and want tabs that remain editable in your codebase.
  • You need keyboard-aware tab behavior backed by Radix UI.
  • You want both horizontal and vertical layouts or a line-style tab treatment.

Skip it if

  • Your project does not use Tailwind utilities and you do not want to translate the styling.
  • You want an isolated package that works without local aliases, theme tokens, and utility helpers.
  • Your tab labels must fit narrow screens without custom overflow or wrapping work.

In a non-shadcn project, add React, radix-ui, class-variance-authority, Tailwind CSS, a compatible cn helper and path alias, plus the referenced shadcn color and state tokens. Mark the file as a client component where the framework requires it, and add responsive overflow or wrapping rules for narrow tab lists.
