Combobox

A single input field that combines the functionality of a select and input.

Framework

Anatomy

To set up the combobox correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the Combobox component in your project. Let's take a look at the most basic example

import { useMemo, useState } from 'react'
import { Combobox, Portal, createListCollection } from '@ark-ui/react'

const initialItems = ['React', 'Solid', 'Vue']

export const Basic = () => {
  const [items, setItems] = useState(initialItems)

  const collection = useMemo(() => createListCollection({ items }), [items])

  const handleInputChange = (details: Combobox.InputValueChangeDetails) => {
    setItems(
      initialItems.filter((item) => item.toLowerCase().includes(details.inputValue.toLowerCase())),
    )
  }

  return (
    <Combobox.Root collection={collection} onInputValueChange={handleInputChange}>

Using the Field Component

The Field component helps manage form-related state and accessibility attributes of a combobox. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility.

import { Combobox, Field, createListCollection } from '@ark-ui/react'

export const WithField = (props: Field.RootProps) => {
  const collection = createListCollection({ items: ['React', 'Solid', 'Vue'] })

  return (
    <Field.Root {...props}>
      <Combobox.Root collection={collection}>
        <Combobox.Label>Label</Combobox.Label>
        <Combobox.Control>
          <Combobox.Input />
          <Combobox.Trigger>Open</Combobox.Trigger>
          <Combobox.ClearTrigger>Clear</Combobox.ClearTrigger>
        </Combobox.Control>
        <Combobox.Positioner>
