8-bit Combo Box
The supplied registry files do not define or export a ComboBox component. They provide 8-bit-styled Button and Popover wrappers, so no combo-box-specific API or behavior can be documented from this source.

Installed with shadcn add · 1 workaround · theme from the install docs
- applied the registry's theme (tokens, fonts and CSS from the registry preview settings)
Installation
pnpm dlx shadcn@latest add @8bitcn/combo-box
Requires @8bitcn in the registries of your components.json (shadcn adds official directory namespaces automatically).
Usage
usage.tsx
import { Button } from "@/components/ui/8bit/button";import { Popover, PopoverContent, PopoverTrigger } from "@/components/ui/8bit/popover";export function RetroPopoverExample() { return ( <Popover> <PopoverTrigger asChild> <Button>Open</Button> </PopoverTrigger> <PopoverContent>Content</PopoverContent> </Popover> );}- Use the supplied Button and Popover wrappers when building a retro-styled interface.
- Use them as building blocks for a combo-box composition only when you provide that composition separately.
- Do not rely on this registry item alone for searchable options, selection state, or combo-box keyboard behavior; those are not implemented in the supplied files.
API reference
PropTypeDefaultDescription
ComboBox propsnone defined—No ComboBox component or ComboBox props type appears in the supplied source. The files define BitButtonProps and BitPopoverProps instead.
BitButtonPropsButtonHTMLAttributes<HTMLButtonElement> & VariantProps<typeof buttonVariants> & { asChild?: boolean; ref?: Ref<HTMLButtonElement> }—Props for the supplied 8-bit Button wrapper. Its variant options are default, destructive, outline, secondary, ghost, and link; size options are default, sm, lg, and icon; font options are normal and retro. The default variant and size are default.
BitPopoverPropsReact.ComponentProps<typeof PopoverPrimitive.Content> & VariantProps<typeof popOverVariants>—Props for the supplied 8-bit PopoverContent wrapper. It accepts the underlying Radix Popover Content props and a font option of normal or retro; the font variant defaults to retro.
Accessibility
- The Button wrapper forwards native button attributes, including standard accessible naming and disabled-state attributes.
- The Popover wrapper delegates to the shadcn/Radix Popover primitives; use an appropriately named trigger and verify the composed interface's keyboard and focus behavior.
- No combo-box option roles, selected-state semantics, or keyboard interaction are implemented in the supplied files.
- Decorative button and popover border elements are marked aria-hidden so they are not announced.
