Kotak kombo

Kotak masukan dengan fitur autocomplete yang menyaring pilihan saat Anda mengetik — seperti pemilih negara, kotak masukan tag, dan daftar pilihan panjang — dengan garis tepi dan bayangan bergaya neobrutalis.

"use client"

import {

Combobox memadukan input teks dengan daftar popup terfilter — ketik untuk menyaring, sorot, lalu pilih. Ia dibangun di atas primitif Base UI Combobox (dipakai kedua backend — Radix UI tidak menyediakan combobox) dan ditata dengan resep neobrutalis: garis tepi tebal, bayangan keras, dan tipografi tebal.

Gunakan saat:

Select yang panjang — negara, zona waktu, mata uang: daftar apa pun yang terlalu panjang untuk digulir di select biasa.
Pemilih tag dan penanggung jawab — multiple dengan chip untuk label, rekan tim, kategori.
Pencarian record — melompat ke pelanggan, repo, atau dokumen dengan mengetik sebagian namanya.

Penggunaan

import {
  Combobox,
  ComboboxContent,
  ComboboxEmpty,
  ComboboxInput,
  ComboboxItem,
  ComboboxList,
} from "@/components/ui/combobox"

const frameworks = ["Next.js", "SvelteKit", "Nuxt.js", "Remix", "Astro"]
 
export function ExampleCombobox() {
  return (
    <Combobox items={frameworks}>
      <ComboboxInput placeholder="Select a framework" />
      <ComboboxContent>
        <ComboboxEmpty>No items found.</ComboboxEmpty>
        <ComboboxList>
          {(item) => (
            <ComboboxItem key={item} value={item}>
              {item}
            </ComboboxItem>
          )}
        </ComboboxList>
      </ComboboxContent>
    </Combobox>
  )
}

Komposisi

Sederhana

Input satu baris dan daftar datar (lihat Dasar).

Combobox
├── ComboboxInput
└── ComboboxContent
    ├── ComboboxEmpty
    └── ComboboxList
        ├── ComboboxItem
        └── ComboboxItem

Dengan Chip

Pilihan ganda dengan multiple, chip, dan input chip (lihat Multipel).

Combobox
├── ComboboxChips
│   ├── ComboboxValue
│   │   └── ComboboxChip
│   └── ComboboxChipsInput
└── ComboboxContent
    ├── ComboboxEmpty
    └── ComboboxList
        ├── ComboboxItem
        └── ComboboxItem

Dengan Grup dan Koleksi

Item bersarang per grup menggunakan ComboboxCollection di dalam setiap ComboboxGroup, dengan pemisah antar grup (lihat Grup).

Combobox
├── ComboboxInput
└── ComboboxContent
    ├── ComboboxEmpty
    └── ComboboxList
        ├── ComboboxGroup
        │   ├── ComboboxLabel
        │   └── ComboboxCollection
        │       ├── ComboboxItem
        │       └── ComboboxItem
        ├── ComboboxSeparator
        └── ComboboxGroup
            ├── ComboboxLabel
            └── ComboboxCollection
                ├── ComboboxItem
                └── ComboboxItem

Item Kustom

Gunakan itemToStringValue ketika item Anda berupa objek.

import * as React from "react"
 
import {
  Combobox,
  ComboboxContent,
  ComboboxEmpty,
  ComboboxInput,
  ComboboxItem,
  ComboboxList,
} from "@/components/ui/combobox"
 
type Framework = {
  label: string
  value: string
}
 
const frameworks: Framework[] = [
  { label: "Next.js", value: "next" },
  { label: "SvelteKit", value: "sveltekit" },
  { label: "Nuxt", value: "nuxt" },
]
 
export function ExampleComboboxCustomItems() {
  return (
    <Combobox
      items={frameworks}
      itemToStringValue={(framework) => framework.label}
    >
      <ComboboxInput placeholder="Select a framework" />
      <ComboboxContent>
        <ComboboxEmpty>No items found.</ComboboxEmpty>
        <ComboboxList>
          {(framework) => (
            <ComboboxItem key={framework.value} value={framework}>
              {framework.label}
            </ComboboxItem>
          )}
        </ComboboxList>
      </ComboboxContent>
    </Combobox>
  )
}

Pilihan Ganda

Gunakan multiple dengan chip untuk perilaku pilihan ganda.

import * as React from "react"
 
import {
  Combobox,
  ComboboxChip,
  ComboboxChips,
  ComboboxChipsInput,
  ComboboxContent,
  ComboboxEmpty,
  ComboboxInput,
  ComboboxItem,
  ComboboxList,
  ComboboxValue,
} from "@/components/ui/combobox"
 
const frameworks = ["Next.js", "SvelteKit", "Nuxt.js", "Remix", "Astro"]
 
export function ExampleComboboxMultiple() {
  const [value, setValue] = React.useState<string[]>([])
 
  return (
    <Combobox
      items={frameworks}
      multiple
      value={value}
      onValueChange={setValue}
    >
      <ComboboxChips>
        <ComboboxValue>
          {value.map((item) => (
            <ComboboxChip key={item}>{item}</ComboboxChip>
          ))}
        </ComboboxValue>
        <ComboboxChipsInput placeholder="Add framework" />
      </ComboboxChips>
      <ComboboxContent>
        <ComboboxEmpty>No items found.</ComboboxEmpty>
        <ComboboxList>
          {(item) => (
            <ComboboxItem key={item} value={item}>
              {item}
            </ComboboxItem>
          )}
        </ComboboxList>
      </ComboboxContent>
    </Combobox>
  )
}

Contoh

Dasar

Combobox sederhana dengan daftar framework.

"use client"

import {

Multipel

Combobox dengan pilihan ganda menggunakan multiple dan ComboboxChips.

Next.js

"use client"

import * as React from "react"

Tombol Hapus

Gunakan prop showClear untuk menampilkan tombol hapus.

"use client"

import {

Grup

Gunakan ComboboxGroup dan ComboboxSeparator untuk mengelompokkan item.

"use client"

import {

Item Kustom

Anda dapat merender komponen kustom di dalam ComboboxItem.

"use client"

import {

Tidak Valid

Gunakan prop aria-invalid untuk membuat combobox tidak valid.

"use client"

import {

Nonaktif

Gunakan prop disabled untuk menonaktifkan combobox.

"use client"

import {

Sorot Otomatis

Gunakan prop autoHighlight untuk menyorot item pertama secara otomatis saat memfilter.

"use client"

import {

Anda dapat memicu combobox dari tombol atau komponen lain menggunakan prop render. Pindahkan ComboboxInput ke dalam ComboboxContent.

"use client"

import { Button } from "@/components/ui/button"

Grup Input

Anda dapat menambahkan addon ke combobox menggunakan komponen InputGroupAddon di dalam ComboboxInput.

"use client"

import { GlobeIcon } from "lucide-react"

RTL

Untuk mengaktifkan dukungan RTL di Neobrutalism, lihat panduan konfigurasi RTL.

"use client"

import * as React from "react"

Aksesibilitas

Combobox mengimplementasikan pola Combobox WAI-ARIA: inputnya membawa role="combobox" dengan aria-expanded dan aria-activedescendant yang melacak opsi tersorot di popup role="listbox", sehingga fokus DOM tidak pernah meninggalkan input.

Interaksi keyboard:

Tombol	Aksi
Karakter yang dapat dicetak	Menyaring daftar opsi
`ArrowDown` / `ArrowUp`	Membuka popup dan memindahkan sorotan ke bawah / ke atas
`Enter`	Memilih opsi yang tersorot
`Escape`	Menutup popup tanpa mengubah nilai
`Backspace` pada input chip yang kosong	Menghapus chip terakhir (mode `multiple`)
