Code Block

Language Segments

The same example in TypeScript, JavaScript and Python: a segmented switch whose thumb slides over to the selected button.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • the example heading through title
  • the initially open language through defaultLanguage
  • the radio group name through group when a page holds several such blocks

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Language Segments with Cursor or Claude Code?
Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
What does Language Segments depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Language Segments?
Adapt: the example heading through title; the initially open language through defaultLanguage; the radio group name through group when a page holds several such blocks. Keep as installed: the local --vibeui-codeblock-016-* palette — do not swap it for your theme tokens; the thumb as a separate layer: recolouring the captions instead of moving it loses the motion itself; the radio buttons as the source of state: with useState the block stops working before hydration.
Is Language Segments free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

npx shadcn@latest add https://vibeui.club/r/pro/codeblock-016.json

This command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options

Technical notes

The component is self-contained: one file, zero dependencies, its own palette in the local --vibeui-codeblock-016-* variables. Server component: the state is held by a radio group, and the panel and the thumb position are selected through :has() by the value of the checked button, so switching works before hydration. The thumb is a separate layer under the labels: it is not redrawn but travels with a transform, so a language change reads as a single movement. The thumb width is computed from three segments, and the labels are shortened to TS, JS and PY so that the switch does not sprawl across the header.
