Input
Required Field Error
A required field with an asterisk by the label (plus hidden text for screen readers) and an error message below it: the error appears after the empty field loses focus, not on every keystroke.
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 errorText copy for your own wording
- the starting defaultValue
- the accent through the accent prop
A link for your AI agent: preview, code and instructions.

FAQ
- How do I add Required Field Error 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 Required Field Error depend on?
- No npm packages beyond React and Tailwind CSS.
- What can I change in Required Field Error?
- Adapt: the label, placeholder and errorText copy for your own wording; the starting defaultValue; the accent through the accent prop. Keep as installed: the local --vibeui-input-031-* palette — do not swap it for your theme tokens; the touched state — the error must not flash from a single click into the field and back out, only after a real attempt to fill it in and leave; the hidden span reading 'required field' next to the asterisk — the asterisk itself is aria-hidden and unreadable by a screen reader without it.
- Is Required Field Error free?
- Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

Technical notes
The component is self-contained: one file, no dependencies, its own palette in local variables --vibeui-input-031-*. A client component: "use client" (the touched state). The asterisk is marked aria-hidden, and beside it lies a visually hidden (clip-path, not display:none) span reading ", required field" for a screen reader — so the whole label reads as "Recipient name, required field". The error is conditional on touched && empty: until the first loss of focus the field is not highlighted, aria-describedby points at the error text only while it is shown, and role="alert" on the p with the error ensures it is announced when it appears.
