Autocomplete
An autocomplete combines a text input with a listbox, allowing users to filter a list of options to items matching a query.
Import
NextUI exports 3 autocomplete-related components:
- Autocomplete: The main component, which is a wrapper for the other components.
- AutocompleteSection: The component that contains a group of autocomplete items.
- AutocompleteItem: The component that represents a autocomplete item.
Usage
Dynamic items
Autocomplete follows the Collection Components API, accepting both static and dynamic collections.
- Static: The usage example above shows the static implementation, which can be used when the full list of options is known ahead of time.
- Dynamic: The example below can be used when the options come from an external data source such as an API call, or update over time.
Disabled
Disabled Items
You can disable specific items by using the disabledKeys
property.
Required
If you pass the isRequired
property to the autocomplete, it will have a danger
asterisk at
the end of the label and the autocomplete will be required.
Sizes
Colors
Variants
Label Placements
You can change the position of the label by setting the labelPlacement
property to inside
, outside
or outside-left
.
Note: If the
label
is not passed, thelabelPlacement
property will beoutside
by default.
Start Content
You can use the startContent
and endContent
properties to add content to the start and end of
the autocomplete.
Item Start & End Content
Since the Autocomplete
component uses the Listbox component under the hood, you can
use the startContent
and endContent
properties of the AutocompleteItem
component to add content to the start
and end of the autocomplete item.
Custom Value
By default, Autocomplete
doesn't allow users to specify a value that doesn't exist in the list of options and will
revert the input value to the current selected value on blur. By specifying allowsCustomValue
, this behavior is
suppressed and the user is free to enter any value within the field.
Custom Selector Icon
By default the seleautocompletet uses a chevron-down
icon as the selector icon which rotates when the autocomplete is open. You can
customize this icon by passing a custom one to the selectorIcon
property.
Note: Use the
disableSelectionIconRotation
property to disable the rotation of the icon.
Without Scroll Shadow
Autocomplete component uses the ScrollShadow under the hood to show a shadow when the autocomplete content is scrollable.
You can disable this shadow by passing using the scrollShadowProps
property.
Note: You can also use the
showScrollIndicators
property to disable the scroll indicators.
With Description
You can add a description to the autocomplete by passing the description
property.
With Error Message
You can combine the isInvalid
and errorMessage
properties to show an invalid autocomplete.
Events
The Autocomplete
component supports selection via mouse, keyboard, and touch. You can handle all of these
via the onSelectionChange
prop. Autocomplete
will pass the selected key to the onSelectionChange handler.
Additionally, ComboBox accepts an onInputChange
prop which is triggered whenever the value is edited by the user,
whether through typing or option selection.
The example below uses onSelectionChange
and onInputChange
to update the selection and input value stored in
React state.
Controlled
You can use the selectedKey
and onSelectionChange
properties to control the select value.
Fully Controlled
By passing in inputValue
, selectedKey
, and items
to the Autocomplete
you can control exactly what your Autocomplete
should display.
The following example shows how you would create a controlled Autocomplete
, controlling everything from the selected value
selectedKey
to the combobox options items
.
We recommend using the useFilter
hook from @react-aria/i18n to manage the filtering of the items.
import {useFilter} from "@react-aria/i18n";
Note: It is important to note that you don't have to control every single aspect of a
Autocomplete
. If you decide to only control a single property of theAutocomplete
, be sure to provide the change handler for that prop as well e.g. controllingselectedKey
would requireonSelectionChange
.
Custom Items
You can customize the autocomplete items by modifying the AutocompleteItem
children.
Custom Filtering
By default, Autocomplete
uses a "contains"
function from useFilter to filter the
list of options. This can be overridden using the defaultFilter
prop, or by using the items
prop to control the
filtered list. When items
is provided rather than defaultItems
, Autocomplete
does no filtering of its own.
The following example uses the defaultFilter
prop to filter the list of options using a custom filter function.
Asynchronous Filtering
Autocomplete supports asynchronous filtering, in the example below we are using the useAyncList function from react-aria to handle asynchronous loading and filtering of data from a server.
import {useAsyncList} from "@react-stately/data";
Asynchronous Loading
Autocomplete supports asynchronous loading, in the example below we are using a custom hook to fetch the Pokemon API data in combination with the useInfiniteScroll
hook to load more data when the user reaches the end of the list.
The isLoading
prop is used to show a loading indicator instead of the selector icon when the data is being fetched.
import {useInfiniteScroll} from "@nextui-org/use-infinite-scroll";
With Sections
You can use the AutocompleteSection
component to group autocomplete items.
Custom Sections Style
You can customize the sections style by using the classNames
property of the AutocompleteSection
component.
Customizing the Autocomplete
You can customize any slot of the autocomplete by using the classNames
property. Autocomplete
component also provides the popoverProps, listboxProps, inputProps
properties to customize the popover, listbox and input components.
Slots
- base: The main wrapper of the autocomplete. This wraps the input and popover components.
- listboxWrapper: The wrapper of the listbox. This wraps the listbox component, this slot is used on top of the scroll shadow component.
- listbox: The listbox component. This is the component that wraps the autocomplete items.
- popoverContent: The popover content slot. Use this to modify the popover content styles.
- endContentWrapper: The wrapper of the end content. This wraps the clear button and selector button.
- clearButton: The clear button slot.
- selectorButton: The selector button slot.
Data Attributes
Autocomplete
has the following attributes on the base
element:
- data-invalid:
When the autocomplete is invalid. Based on
isInvalid
prop. - data-open: Indicates if the autocomplete's popover is open.
Autocomplete
has the following attributes on the selectorButton
element:
- data-open: Indicates if the autocomplete's popover is open.
Autocomplete
has the following attributes on the clearButton
element:
- data-visible: Indicates if the autocomplete's clear button is visible. By default it is visible when hovering the autocomplete and when the autocomplete has a value (desktop), or when the autocomplete has a value (mobile).
AutocompleteItem
has the following attributes on the base
element:
- data-disabled:
When the autocomplete item is disabled. Based on autocomplete
