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

Custom Items

Use itemToStringValue when your items are objects.

tsx
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>
  )
}

Multiple Selection

Use multiple with chips for multi-select behavior.

tsx
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>
