Form Group
Structural legend/description/error grouping for related controls without becoming one accessible parent element.
Identity
Section titled “Identity”- Category: Forms & selection
- Status: stable public Registry/export-map component family
- Targets: iOS · Android · Web, subject to the compatibility contract
- Prerequisites:
@beemvp/beeui-uiinstalled (or this component’s source copied via the Registry CLI below) and, on Web, the BeeUI Tailwind/Uniwind theme CSS loaded — see Start for full platform setup. - Source:
packages/ui/src/components/form-group.tsx
Import
Section titled “Import”import { FormGroup } from '@beemvp/beeui-ui';There is no documented deep/private source import. For source ownership from a BeeUI checkout:
pnpm beeui add form-groupRegistry (used throughout this page) is BeeUI’s source-ownership manifest — registry/registry.json — that the pnpm beeui/@beemvp/beeui-cli CLI reads to copy a component’s real source into your app and rewrite its internal imports; it is not an npm package index. This component’s own Registry entry: registry/registry.json.
Composition and public API
Section titled “Composition and public API”- Primary export:
FormGroup- Also routed here, outside the Registry family:
form-group
- Package export subpath:
@beemvp/beeui-ui/form-group
- Also routed here, outside the Registry family:
Exported types: FormGroupProps
The generated API inventory is mechanically joined to packages/ui/src/index.ts, Registry metadata, and the component reference contract. Each type’s field table below is parsed directly from that source, not a second hand-maintained copy; for the fuller behavior narrative see the canonical component behavior catalog.
State and behavior contract
Section titled “State and behavior contract”Structural legend/description/error/disabled grouping; it stays accessible={false} (there is no generic native fieldset role) and never mutates descendant state directly — only semantic-aware children such as RadioGroup opt into consuming its context.
FormGroupProps
Section titled “FormGroupProps”| Prop | Type | Default | Description |
|---|---|---|---|
children (required) |
React.ReactNode |
— | Content rendered inside this element. The family’s composition section states which children it expects. |
className |
string |
— | Extra utility classes, merged after the component’s own via cn(...), so they win on conflict. An escape hatch for source-owned and application work, not a cross-engine portability guarantee. |
description |
string |
— | Secondary supporting text rendered beneath the primary label or title. |
disabled |
boolean |
false |
ORed into a RadioGroup rendered as children, disabling every Radio inside it. Defaults to false. |
error |
string |
— | Shown instead of description, styled destructively, when invalid is true. |
invalid |
boolean |
false |
Switches the helper text below children from description to error. Defaults to false. |
legend (required) |
string |
— | Heading text for the group, rendered as a Label above children (e.g. “Shipping method”). |
legendNativeID |
string |
— | nativeID for the rendered legend Label, used to build accessibilityLabelledBy links (e.g. from a RadioGroup rendered as children). Defaults to a generated, stable-per-mount ID. |
required |
boolean |
false |
Renders the legend with a required indicator and, when requiredAccessibilityLabel is also supplied, appends it to the accessible name. Defaults to false. |
requiredAccessibilityLabel |
string |
'required' |
Text appended to the legend’s accessible name when required is true (e.g. “Shipping method, required”). No default — omit to expose required only through the group’s own required semantics on its interactive descendants, without injecting English copy. |
Also carries every prop of Omit<ViewProps, 'accessibilityRole' | 'accessible' | 'children' | 'role'> — that upstream contract is not reproduced here.
The executable fixtures below are the source-grounded usage examples; consumers should not infer state ownership from DOM structure or another UI library.
Provider and dependencies
Section titled “Provider and dependencies”- No additional provider is required by this family.
BeeUIProviderremains the recommended application root. - Peer/native dependencies visible to this Registry item:
react,react-native - Registry dependency closure:
core-cn,form-group-context,label,text,theme - Safe-area ownership remains explicit: shell surfaces touching system edges opt into
SafeArea; components do not silently invent app-shell insets. - Web consumers load the BeeUI semantic theme CSS as documented in Web onboarding.
Platform behavior
Section titled “Platform behavior”This family ships no platform-specific file, but its source branches on Platform, so some behavior differs by target.
The same public family is exposed across the supported target matrix; meaningful platform differences remain governed by the compatibility contract.
Evidence classes are not equal and this page does not blur them: Web behavior is exercised in a real browser, while iOS and Android carry package/export and native-compile evidence, which is not device-runtime proof. The compatibility contract records which class each claim rests on.
Accessibility
Section titled “Accessibility”- Roles this family assigns:
alert,group— set inform-group.tsxby the components themselves, not by the caller. - Accessibility states and properties it sets:
accessibilityLabel,accessibilityLabelledBy,accessibilityLiveRegion,describedby(Web),disabled,invalid(Web),labelledby(Web) — read fromform-group.tsx.
Keyboard/focus behavior, announcements, Dynamic Type/Web zoom, RTL and reduced-motion expectations are not derived here — see Accessibility overview, Keyboard & focus, RTL/localization and Large text & zoom. BeeUI does not claim universal accessibility certification from automated tests.
Styling and theming
Section titled “Styling and theming”- Style axes: none of its own — its appearance comes from tokens and your own classes; it also carries
Omit<ViewProps, 'accessibilityRole' | 'accessible' | 'children' | 'role'>. - Class-name surfaces:
className.
Colors, spacing and typography come from semantic tokens rather than from values written here — see Theming and Density. A className is an escape hatch for source-owned and application work, not a cross-engine portability guarantee.
Executable examples
Section titled “Executable examples”- Primary executable fixture:
apps/showcase/__tests__/checkbox-radio-field-form-group-context.test.tsx - Additional fixture:
apps/showcase/__tests__/field-label-accessible-name-dedup.test.tsx - Additional fixture:
apps/showcase/__tests__/form-group-checkbox-list-group-semantics.test.tsx - Additional fixture:
apps/showcase/__tests__/issue-15-alert-dialog-form-group.test.tsx
Addressable examples
Section titled “Addressable examples”Each link below opens the Showcase at that exact example, not at the top of the gallery:
basic— smallest meaningful complete usage
The Showcase links demonstrate Web behavior; use the native-preview guide for real simulator/emulator/device paths.
Live Web preview
Section titled “Live Web preview”This frame loads the real BeeUI Web Showcase on demand; it is not a second docs-only implementation. It proves browser behavior only. Use native preview for iOS/Android simulator, emulator or device paths.
Composition anatomy
Section titled “Composition anatomy”- Family root / primary export:
FormGroup- Exported type surface:
FormGroupProps
- Exported type surface:
The tree above is ordinary document structure so it remains readable with keyboard and assistive technology; it is derived from the real public export family rather than a canvas-only diagram.
Verified example source
Section titled “Verified example source”These are the parts of the typechecked runtime Showcase fixture behind this live preview — apps/showcase/component-gallery/component-gallery.tsx, 1103 lines — where Form Group is actually used: 34 lines in 1 place. Each block is copied verbatim from the line range named above it, so it is the same executable source, not a retelling of it. The rest of that file exercises other families and is not reproduced here.
Imports the examples below need (a filtered subset of the fixture’s own top-level imports):
import { Checkbox, FormGroup, Radio, RadioGroup } from '@beemvp/beeui-ui';import * as React from 'react';Fixture state this block reads (same file, lines 460, 462):
const [assignedStores, setAssignedStores] = React.useState<string[]>([]); const [plan, setPlan] = React.useState<'starter' | 'pro'>('starter'); <FormGroup description="The group owns legend/guidance metadata while each radio stays independently discoverable." legend="Subscription plan" required > <RadioGroup onValueChange={(value) => setPlan(value as 'starter' | 'pro')} value={plan} > <Radio label="Starter plan" value="starter" /> <Radio label="Pro plan" value="pro" /> </RadioGroup> </FormGroup> <FormGroup error="Select at least one store." invalid={assignedStores.length === 0} legend="Assign to stores" required testID="stores-form-group" > {['Store A', 'Store B', 'Store C'].map((store) => ( <Checkbox checked={assignedStores.includes(store)} key={store} label={store} onCheckedChange={(checked) => setAssignedStores((current) => checked ? [...current, store] : current.filter((value) => value !== store), ) } testID={`stores-checkbox-${store.replace(/\s+/g, '-').toLowerCase()}`} /> ))} </FormGroup>Open the fixture itself for the full surrounding component. For a smaller app-specific example, start from the imports and fixture-state blocks above and keep only the state your screen owns.
Limitations
Section titled “Limitations”RadioGroup is the only component in the package that reads this group’s context, so its disabled, invalid and legend link reach a radio group and nothing else: a checkbox, switch or input nested in a form group is unaffected and has to be wired by hand. The group is deliberately not one accessible element and accepts no role override.
