Checkbox
Controlled boolean/indeterminate checkbox; enabled usage without onCheckedChange warns in development.
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/checkbox.tsx
Import
Section titled “Import”import { Checkbox, checkboxIndicatorVariants } from '@beemvp/beeui-ui';There is no documented deep/private source import. For source ownership from a BeeUI checkout:
pnpm beeui add checkboxRegistry (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”- Family exports:
CheckboxcheckboxIndicatorVariants- Also routed here, outside the Registry family:
checkbox
- Package export subpath:
@beemvp/beeui-ui/checkbox
- Also routed here, outside the Registry family:
Exported types: CheckboxProps, CheckboxValue
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”Controlled boolean/indeterminate checked/onCheckedChange checkbox; enabling it without onCheckedChange warns in development instead of silently doing nothing, and disabled blocks both press handling and the accessibility toggle action.
CheckboxProps
Section titled “CheckboxProps”| Prop | Type | Default | Description |
|---|---|---|---|
checked |
CheckboxValue |
false |
The checkbox’s state: true (checked), false (unchecked), or 'indeterminate' (a dash, e.g. a “select all” with a partial selection). Always controlled by the caller; defaults to false. |
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. |
indicatorClassName |
string |
— | Applied to the checkbox’s own box, not its label. |
label |
string |
— | The visible text naming this element, and the accessible name unless one is set explicitly. |
labelClassName |
string |
— | Extra utility classes for the label text specifically, merged after the component’s own. |
onCheckedChange |
(checked: boolean) => void |
— | Called with the next checked state (true/false, never 'indeterminate') when pressed. Toggles from 'indeterminate' to true. |
Also carries every prop of Omit<PressableProps, 'accessibilityRole' | 'role' | 'children' | 'onPress'> — that upstream contract is not reproduced here.
Related exported types:
CheckboxValue— alias ofboolean | 'indeterminate'.
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,text,theme,use-required-callback-warning - 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, and its own source takes no Platform branch.
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:
checkbox— set incheckbox.tsxby the components themselves, not by the caller. - Accessibility states and properties it sets:
accessibilityHint,accessibilityLabel,accessibilityLabelledBy,accessible,checked,disabled,required— read fromcheckbox.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<PressableProps, 'accessibilityRole' | 'role' | 'children' | 'onPress'>. - Class-name surfaces:
className,indicatorClassName,labelClassName.
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:

Addressable examples
Section titled “Addressable examples”Each link below opens the Showcase at that exact example, not at the top of the gallery:
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

- Public composition parts / helpers:
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 Checkbox is actually used: 19 lines in 2 places. 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 } from '@beemvp/beeui-ui';import * as React from 'react';Fixture state this block reads (same file, line 459):
const [accepted, setAccepted] = React.useState(false); <Checkbox checked={accepted} label="Accept terms" onCheckedChange={setAccepted} /> <Checkbox checked disabled label="Managed by policy" onCheckedChange={() => undefined} testID="checkbox-managed-state" />Fixture state this block reads (same file, line 460):
const [assignedStores, setAssignedStores] = React.useState<string[]>([]); <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()}`} />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”Pressing an indeterminate checkbox reports true: onCheckedChange is never called with the indeterminate value, so the component can never return to that state on its own — the caller has to set checked back. label accepts a string only, and press handling is owned here.
