Code Block

Wrap Switch

A code block with a switch for wrapping long lines: a hidden checkbox holds the state, :has() changes the layout, no JavaScript needed.

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 block code through code and the heading through title
  • the switch caption through label
  • the initial state through wrapByDefault

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

FAQ

How do I add Wrap Switch 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 Wrap Switch depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Wrap Switch?
Adapt: the block code through code and the heading through title; the switch caption through label; the initial state through wrapByDefault. Keep as installed: the local --vibeui-codeblock-008-* palette — do not swap it for your theme tokens; the checkbox as the source of state: with useState the block stops working before hydration; hiding the input with clip-path rather than display:none — otherwise the switch leaves the tab order.
Is Wrap Switch 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-008.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-008-* variables. Server component: the toggle state is held by a native checkbox, and the root :has(input:checked) selector switches the code from white-space: pre to pre-wrap and removes the horizontal scrolling along with it. The checkbox is hidden with clip-path, so it stays reachable from the keyboard; the switch is drawn from a span with ::after, and the focus ring is attached to the label through :has(input:focus-visible). The theme comes from the surrounding color-scheme through light-dark(): the block has no surface by default, and the header and the switch track are drawn with translucent overlays.
