Input

Field Explainer

A field with a help button on the right: clicking it expands an explanation inline below the frame, pushing neighbouring elements down instead of covering them.

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 label, placeholder and explanation copy
  • the name prop and defaultValue
  • the hint text under the group

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

FAQ

How do I add Field Explainer 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 Field Explainer depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Field Explainer?
Adapt: the label, placeholder and explanation copy; the name prop and defaultValue; the hint text under the group. Keep as installed: the local --vibeui-inputgroup-022-* palette — do not swap it for your theme tokens; the collapsed borders: neighbours carry a negative margin so the parts share one line instead of two; the grid-template-rows (0fr → 1fr) expansion — animating an auto height without measuring pixels in JS.
Is Field Explainer 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/inputgroup-022.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, no dependencies, its own palette in the local --vibeui-inputgroup-022-* variables. Client-side: "use client" for the sake of the value and the open panel state. The button on the right toggles aria-expanded and expands the explanation panel through grid-template-rows (0fr → 1fr) — the technique animates the height without measuring pixels in JS and without position:absolute over the neighbouring elements. aria-controls ties the button to the panel, and aria-describedby on the field covers both the panel and the ordinary hint.
