Usage
usage.tsx
import { Checkbox } from "@/components/ui/8bit/checkbox";export function Example() { return <Checkbox aria-label="Enable sound effects" />;}- Use when a form needs a checkbox with a retro, pixel-art-inspired visual style.
- Use alongside other 8-bit components for a consistent game-like interface.
- Use the normal font option when the retro typography treatment is not desired.
Examples
Labeled option
Use a label associated with the checkbox for an accessible form control.
labeled-option.tsx
import { Checkbox } from "@/components/ui/8bit/checkbox";export function SoundOption() { return ( <div className="flex items-center gap-2"> <Checkbox id="sound" /> <label htmlFor="sound">Enable sound effects</label> </div> );}Normal font variant
Disable the retro font class while keeping the checkbox's pixel-style frame.
normal-font-variant.tsx
import { Checkbox } from "@/components/ui/8bit/checkbox";export function NewsletterOption() { return <Checkbox font="normal" aria-label="Subscribe to the newsletter" />;}Disabled option
Forward the Radix Checkbox Root disabled prop to prevent interaction.
disabled-option.tsx
import { Checkbox } from "@/components/ui/8bit/checkbox";export function LockedOption() { return <Checkbox disabled aria-label="Locked setting" />;}API reference
PropTypeDefaultDescription
font"normal" | "retro"—Selects the font variant. When omitted, the component applies the retro class; `normal` omits it. The variant is declared through `checkboxVariants`.
asChildboolean—Inherited from the Radix Checkbox Root props and explicitly included in `BitCheckboxProps`; it is forwarded to the underlying shadcn Checkbox.
classNamestring—Inherited from the Radix Checkbox Root props. The component applies this class to both its outer frame wrapper and the underlying Checkbox.
Root propsReact.ComponentProps<typeof CheckboxPrimitive.Root>—All props accepted by the Radix Checkbox Root are supported and forwarded to the underlying shadcn Checkbox, including its checked-state, change-handler, disabled, required, name, and value props.
Accessibility
- Radix Checkbox Root props are forwarded, so use its `aria-*`, `disabled`, `required`, and state-related props as appropriate.
- Give the checkbox an accessible name, for example with `aria-label` or a `<label>` associated using matching `id` and `htmlFor` values.
- The decorative border overlay is marked `aria-hidden="true"` and does not add a separate item to the accessibility tree.
