Ejemplo

// Uso simple con CommandSearch
const items = [
  { value: "react", label: "React", group: "Frameworks" },
  { value: "vue", label: "Vue", group: "Frameworks" },
  { value: "typescript", label: "TypeScript", group: "Lenguajes" },
]

<CommandSearch
  items={items}
  placeholder="Buscar tecnologia..."
  onValueChange={(val) => console.log(val)}
/>

// Composable para mayor control
<Command>
  <CommandInput placeholder="Buscar..." value={query} onChange={(e) => setQuery(e.target.value)} />
  <CommandList>
    <CommandEmpty>Sin resultados.</CommandEmpty>
    <CommandGroup heading="Sugerencias">
      <CommandItem selected={selected === "1"} onSelect={() => setSelected("1")}>
        Opcion 1
        <CommandShortcut>⌘K</CommandShortcut>
      </CommandItem>
    </CommandGroup>
  </CommandList>
</Command>

Notas

Implementacion propia (sin dependencia de cmdk) usando primitivos HTML nativos. CommandSearch es el wrapper de alto nivel con filtrado reactivo integrado. El filtrado es case-insensitive sobre label, description y value. Los grupos se renderizan en orden de aparicion en items.
