Combobox
Required Choice
A required choice inside a form: the error shows up only after a submit, is tied to the field through aria-describedby and clears as soon as a row is picked.
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 error copy through errorText and the hint through hintText
- the button caption through submitLabel and the list content through options
- the field caption through label and the placeholder through placeholder
A link for your AI agent: preview, code and instructions.

FAQ
- How do I add Required Choice 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 Choice depend on?
- No npm packages beyond React and Tailwind CSS.
- What can I change in Required Choice?
- Adapt: the error copy through errorText and the hint through hintText; the button caption through submitLabel and the list content through options; the field caption through label and the placeholder through placeholder. Keep as installed: the local --vibeui-combobox-010-* palette — do not swap it for your theme tokens; showing the error only after a submit: highlighting while typing reads as an accusation; aria-invalid together with aria-describedby — without the pair the message is not read next to the field.
- Is Required Choice 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 --vibeui-combobox-010-* palette. The root is a form with noValidate: browser validation cannot check a hand-drawn list, so the checking is done by the submit handler. The error is set only after an attempt to submit, not on every keystroke: telling someone off while they are still filling in the form is the worst thing a field can do. The field gets aria-invalid and an aria-describedby pointing at the message or at the hint, and the message lives in a role="alert" and is therefore spoken without moving focus. Enter in the field selects a row and does not submit the form — otherwise half of the people would submit it having missed the list. After a failed submit focus returns to the field.
