FormGroup — spec

Synthesized from MUI FormGroup. A wrapper for grouping multiple FormControlLabel-wrapped checkboxes. Provides spacing + optional row layout. Doesn't enforce mutual exclusivity (use RadioGroup for that).

When to use

  • Multi-select checkbox groups (filter options, consent checkboxes, multi-day picker).
  • Inside FormControl to group related toggles under one label.

API

<FormControl>
  <FormLabel>관심 도메인 (복수 선택)</FormLabel>
  <FormGroup>
    <FormControlLabel control={<Checkbox />} label="UI/UX" />
    <FormControlLabel control={<Checkbox />} label="브랜드" />
    <FormControlLabel control={<Checkbox />} label="모션" />
  </FormGroup>
</FormControl>
Prop Type Default Description
children ReactNode — FormControlLabel children
row boolean false Layout horizontally (default vertical)

States

Layout primitive — no interactive state of its own.

Tokens consumed

--space-xs   /* gap between rows */
--space-md   /* gap between columns when row */

Accessibility

  • Wrap inside FormControl with FormLabel to give the group an accessible name.
  • For required groups: FormControl required propagates to the FormLabel asterisk.
  • Don't rely on FormGroup alone for labeling — screen readers won't announce the group purpose without a parent label.

Edge cases

  • Many options (10+) — switch to a multi-select Autocomplete or a search-filtered list.
  • row with long labels — wraps to next line; check at narrow viewports (320px).
  • Mixing checkboxes + switches — possible but visually inconsistent; prefer one control type per group.

Code example

<FormControl required component="fieldset">
  <FormLabel component="legend">법적 동의 사항</FormLabel>
  <FormGroup>
    <FormControlLabel
      control={<Checkbox required name="terms" />}
      label="이용약관에 동의해요"
    />
    <FormControlLabel
      control={<Checkbox required name="privacy" />}
      label="개인정보 수집·이용에 동의해요"
    />
    <FormControlLabel
      control={<Checkbox name="marketing" />}
      label="마케팅 수신에 동의해요 (선택)"
    />
  </FormGroup>
</FormControl>

Don't

  • Don't use for radio groups — use RadioGroup (handles name + mutual exclusivity).
  • Don't omit the parent label — the group needs an accessible name.
