}Examples
Grouped preferences
Use the first-child legend to name the group and keep a native label on each control.
Fieldset / Legend
Default
import { Checkbox, Fieldset, FieldsetLegend } from "@gunkin/uiify";
export default function Example() {
return (
<Fieldset>
<FieldsetLegend>Contact preferences</FieldsetLegend>
<Checkbox id="contact-email" label="Email" name="contact" value="email" />
<Checkbox id="contact-sms" label="Text message" name="contact" value="sms" />
</Fieldset>
);
}API
Fieldset
| Prop | Type | Default | Description |
|---|---|---|---|
children | ReactNode | — | Grouped controls and a first-child FieldsetLegend. |
className / style / ref / native fieldset props | native fieldset props | — | Native fieldset props, styles, events, and ref are forwarded. |
render | ReactElement | ((props, state) => ReactElement) | — | Replace the rendered element while keeping behavior and accessibility wiring. |
FieldsetLegend
| Prop | Type | Default | Description |
|---|---|---|---|
children | ReactNode | — | Visible group name rendered as the native legend. |
render | ReactElement | ((props, state) => ReactElement) | — | Replace the rendered element while keeping behavior and accessibility wiring. |
Keyboard
| Key | Action |
|---|
Accessibility
Fieldset and Legend render native fieldset and legend elements. Put FieldsetLegend first to name the group; each contained control still needs its own label. No synthetic group role or hidden legend is added.
