--- title: Combobox description: A versatile input component that combines a text input with a listbox, allowing users to filter a list of options and select single or multiple values. links: source: components/combobox storybook: components-combobox--basic recipe: combobox ark: https://ark-ui.com/react/docs/components/combobox --- ## Usage ```tsx import { Combobox } from "@chakra-ui/react" ``` ```tsx ``` To setup combobox, you might need to import the following hooks: - `useListCollection`: Used to manage the list of items in the combobox, providing helpful methods for filtering and mutating the list. - `useFilter`: Used to provide the filtering logic for the combobox based on [`Intl.Collator`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/Collator) APIs. ## Examples ### Basic The basic combobox provides a searchable dropdown with single selection. ### Sizes Pass the `size` prop to the `Combobox.Root` to change the size of the combobox. ### Variants Pass the `variant` prop to the `Combobox.Root` to change the appearance of the combobox. ### Multiple Pass the `multiple` prop to the `Combobox.Root` to enable multiple selection. This allows users to select multiple items from the list. > When this is set, the combobox will always clear the input value when an item > is selected. ### Async Loading Here's an example of loading the `collection` asynchronously as users type, perfect for API-driven search interfaces. ### Highlight Matching Text Here's an example of composing the `Combobox.Item` and `Highlight` components to highlight matching text in search results. ### Open on Click Use the `openOnClick` prop to open the combobox when the user clicks on the input. ### Custom Objects By default, the combobox collection expects an array of objects with `label` and `value` properties. In some cases, you may need to deal with custom objects. Use the `itemToString` and `itemToValue` props to map the custom object to the required interface. ```tsx const items = [ { country: "United States", code: "US", flag: "πŸ‡ΊπŸ‡Έ" }, { country: "Canada", code: "CA", flag: "πŸ‡¨πŸ‡¦" }, { country: "Australia", code: "AU", flag: "πŸ‡¦πŸ‡Ί" }, // ... ] const { contains } = useFilter({ sensitivity: "base" }) const { collection } = useListCollection({ initialItems: items, itemToString: (item) => item.country, itemToValue: (item) => item.code, filter: contains, }) ``` ### Minimum Characters Use the `openOnChange` prop to set a minimum number of characters before filtering the list. ```tsx e.inputValue.length > 2} /> ``` ### Field Compose the `Combobox` component with the `Field` component to wrap the combobox in a form field. Useful for form layouts. ### Disabled State Pass the `disabled` prop to the `Combobox.Root` to disable the entire combobox. ### Disabled Item Disable specific items in the dropdown, add the `disabled` prop to the collection item. ```tsx {2} const items = [ { label: "Item 1", value: "item-1", disabled: true }, { label: "Item 2", value: "item-2" }, ] const { collection } = useListCollection({ initialItems: items, // ... }) ``` ### Input Group Combine with InputGroup to add icons or other elements. ### Invalid Pass the `invalid` prop to the `Combobox.Root` to show the error state. ### Controlled Value Use the `value` and `onValueChange` props to control the combobox's value programmatically. ### Store An alternative way to control the combobox is to use the `Combobox.RootProvider` component and the `useCombobox` store hook. ```tsx import { Combobox, useCombobox } from "@chakra-ui/react" function Demo() { const combobox = useCombobox() return ( {/* ... */} ) } ``` This way you can access the combobox state and methods from outside the combobox. ### Controlled Open Use the `open` and `onOpenChange` props to control the combobox's open state programmatically. ### Limit Large Datasets The recommended way of managing large lists is to use the `limit` property on the `useListCollection` hook. This will limit the number of rendered items in the DOM to improve performance. ### Virtualization Alternatively, you can leverage virtualization from the `@tanstack/react-virtual` package to render large datasets efficiently. ### Links Use the `asChild` prop to render the combobox items as links. For custom router links, you can customize the `navigate` prop on the `Combobox.Root` component. Here's an example of using the Tanstack Router. ```tsx {8-10} import { Combobox } from "@chakra-ui/react" import { useNavigate } from "@tanstack/react-router" function Demo() { const navigate = useNavigate() return ( { navigate({ to: href }) }} > {/* ... */} ) } ``` ### Rehydrate Value In some cases, where a combobox has a `defaultValue` but the collection is not loaded yet, here's an example of how to rehydrate the value and populate the input value. ### Custom Item Customize the appearance of items in the dropdown with your own components. ### Custom Filter Here's an example of a custom filter that matches multiple properties of an item. ### Custom Animation To customize the animation of the combobox, pass the `_open` and `_closed` prop to the `Combobox.Content` component. ### Within Dialog To use the combobox within a dialog or popover component, avoid wrapping the `Combobox.Positioner` within the `Portal`. ```diff - {/* ... */} - ``` If you use a `Dialog` and have set `scrollBehavior="inside"`, you need to: - Set the combobox positioning to `fixed` to avoid the combobox from being clipped by the dialog. - Set `hideWhenDetached` to `true` to hide the combobox when the trigger is scrolled out of view. ```tsx {/* ... */} ``` ## Props ### Root ### Item
