8-bit Command
An 8-bit-styled wrapper around cmdk command components, with pixel-like framing, retro typography, and a dialog variant for command palettes. It exports the command container, input, list, groups, items, separators, empty state, shortcut, and dialog components.

Usage
usage.tsx
import { Command, CommandEmpty, CommandGroup, CommandInput, CommandItem, CommandList,} from "@/components/ui/8bit/command";export function Example() { return ( <Command> <CommandInput placeholder="Search commands..." /> <CommandList> <CommandEmpty>No results found.</CommandEmpty> <CommandGroup heading="Actions"> <CommandItem>Open settings</CommandItem> </CommandGroup> </CommandList> </Command> );}- For searchable lists of actions or options that benefit from cmdk’s command-menu behavior.
- For a keyboard-accessible command palette presented inside a dialog.
- When a command menu should match an 8-bit or pixel-art visual style.
- For grouped commands, empty results, separators, or shortcut hints in a command list.
API reference
PropTypeDefaultDescription
CommandReact.ComponentProps<typeof CommandPrimitive>—Props are passed through to the underlying cmdk Command. The wrapper also accepts className and merges it into its container and command surface.
CommandDialogReact.ComponentProps<typeof Dialog> & { title?: string; description?: string }—Passes Dialog props to the underlying Dialog. title defaults to "Command Palette" and description defaults to "Search for a command to run..."; children are rendered inside the command surface.
CommandInputReact.ComponentProps<typeof CommandPrimitive.Input>—Props are passed to the cmdk input. className is merged into the input styling; a pixel-art search icon is rendered alongside it.
CommandListReact.ComponentProps<typeof CommandPrimitive.List>—Props are passed to the cmdk list. className is merged with the list styling.
CommandEmptyReact.ComponentProps<typeof CommandPrimitive.Empty>—Props are passed to the cmdk empty-state component.
CommandGroupReact.ComponentProps<typeof CommandPrimitive.Group>—Props are passed to the cmdk group. className is merged with the group styling.
CommandSeparatorReact.ComponentProps<typeof CommandPrimitive.Separator>—Props are passed to the cmdk separator. The wrapper renders the 8-bit Separator inside it; className is merged with the separator styling.
CommandItemReact.ComponentProps<typeof CommandPrimitive.Item>—Props are passed to the cmdk item. className is merged with the item styling.
CommandShortcutReact.ComponentProps<"span">—Span props are passed to the underlying shadcn CommandShortcut; className is merged with the retro styling.
Accessibility
- Command behavior and keyboard interaction come from cmdk; keep commands in a logical order and use clear item text.
- CommandDialog provides a visually hidden DialogTitle and DialogDescription, with defaults that can be replaced using title and description.
- The input accepts cmdk input props; provide an accessible name appropriate to your interface rather than relying only on the search icon.
- Use CommandGroup headings to give related commands context, and ensure custom item content remains understandable without visual styling.
