FAQ
- How do I add Required Marker 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 Marker depend on?
- No npm packages beyond React and Tailwind CSS.
- What can I change in Required Marker?
- Adapt: the label and optionalLabel copy, and the legend footnote text; the placeholder of the required field, plus optionalTitle and optionalPlaceholder of the optional one; requiredTitle and requiredNote — the asterisk expansion for the mouse and for screen readers. Keep as installed: the local --vibeui-field-003-* palette — do not swap it for your theme tokens (bg-background, border-input and the like); light-dark() in the palette: the component has to follow the surrounding color-scheme rather than ship a dark theme of its own; the transparent background by default — the component sits on the page background instead of laying a panel under itself.
- Is Required Marker 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-field-003-*. A server component: there is no state. The asterisk is wrapped in an <abbr title>, doubled by visually hidden text and explained by a footnote under the pair of fields. Beside it stands an optional field with an explicit marker — the pair shows the difference instead of hinting at it. The required field carries required and aria-required.
