Autocomplete

Install: npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1

Version and compatibility

Pinned Mantine Core 9.7.1 requires React and React DOM ^19.2.0 and matching @mantine/hooks@9.7.1, from the installed npm package's peerDependencies. Do not force it into React 18 or another incompatible version. Explain upgrade impact and agree on a plan with the project owner; do not hide conflicts with --force/--legacy-peer-deps. The native Provider enables theme.respectReducedMotion and uses forceColorScheme for light/dark.

Use case

Suggest values while allowing free text.

Native props used by this example

These props are extracted from the local typechecked JSX and grouped by their owning native component. This is not an exhaustive prop list; see pinned source signatures and inheritance below.

Component propExplanation
Autocomplete.disabledDisable user input/action; not equivalent to readOnly.
Autocomplete.errorLocal error display; it does not run validation by itself.
Autocomplete.readOnlyPrevent editing while preserving the read-only interaction.
Autocomplete.labelVisible label or component-specific label content.
Autocomplete.dataLocal options/nodes; keep unique values and native schema.
Autocomplete.placeholderInput hint, not a replacement for a label.

Interaction and state checks

Current scenarios: Default, Disabled, Invalid, Read only. Check actual behavior after selecting supported disabled/error/read-only scenarios; components without those native states do not receive invented universal props. Verify keyboard focus and exits, then connect changed values through the native callback signature.

Business integration boundary

Suggestions do not force the input to be one of the options. Validate business rules separately.

Host setup

Install pinned @mantine/core and @mantine/hooks, import @mantine/core/styles.css at the entry and use MantineProvider. The example's theme/variant are JGuang-authored host props, not universal native component APIs; forceColorScheme synchronizes the app theme. Native implementation source is a reading reference: use npm exports rather than copying internal engines. This batch covers Core, not dates/charts/forms extension packages. Detailed upstream prose remains English.

Runnable usage

import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';

const fruit = ["Apple", "Banana", "Orange"];
function ComponentPreview({ variant = 'Default' }: { variant?: string }) {
const disabled = variant === "Disabled";
const invalid = variant === "Invalid";
const readOnly = variant === "Read only";
return <M.Autocomplete disabled={disabled} error={invalid ? "Choose a fruit / 请选择水果" : undefined} readOnly={readOnly} label="Favorite fruit / 水果" data={fruit} placeholder="Type to search" />;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

Preview states

Default, Disabled, Invalid, Read only

The example uses the native Mantine API. For supported input demos, change the local variant to Disabled, Invalid or Read only; these are example labels, not new component props. Keep the documented data, controlled values, stores and compound children when adapting the example.

Not a searchable select

Autocomplete is not a searchable select, it is a text input with suggestions. Values are not enforced to be one of the suggestions – users can type anything. If you need a searchable select, use the Select component instead. To learn more about the differences between Autocomplete and Select, check the help center article.

Usage

Autocomplete provides users with a list of suggestions based on the input, however users are not limited to suggestions and can type anything.

Loading state

Set loading prop to display a loading indicator. By default, the loader is displayed on the right side of the input. You can change the position with the loadingPosition prop to 'left' or 'right'. This is useful for async operations like API calls, searches, or validations:

Controlled

The Autocomplete value must be a string; other types are not supported. The onChange function is called with a string value as a single argument.

import { useState } from 'react';
import { Autocomplete } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState('');
  return <Autocomplete data={[]} value={value} onChange={setValue} />;
}

Uncontrolled

Autocomplete can be used with uncontrolled forms the same way as a native input element. Set the name attribute to include autocomplete value in FormData object on form submission. To control the initial value in uncontrolled forms, use the defaultValue prop.

Example usage of uncontrolled Autocomplete with FormData:

import { Autocomplete } from '@mantine/core';

function Demo() {
  return (
    <form
      onSubmit={(event) => {
        event.preventDefault();
        const formData = new FormData(event.currentTarget);
        console.log('Autocomplete value:', formData.get('country'));
      }}
    >
      <Autocomplete
        label="Select your country"
        placeholder="Pick one"
        name="country"
        data={['United States', 'Canada', 'Mexico']}
        defaultValue="United States"
      />
      <button type="submit">Submit</button>
    </form>
  );
}

Select first option on change

Set the selectFirstOptionOnChange prop to automatically select the first option in the dropdown when the input value changes. This feature allows users to type a value and immediately press Enter to select the first matching option, without needing to press the arrow down key first.

autoSelectOnBlur

Set the autoSelectOnBlur prop to automatically select the highlighted option when the input loses focus. To see this feature in action: select an option with the up/down arrows, then click outside the input:

Sort options

By default, options are sorted by their position in the data array. You can change this behavior with the filter function:

Fuzzy search with fuse.js

You can implement fuzzy search using the fuse.js library to match options even with typos or partial matches:

renderOption

The renderOption callback allows you to customize option rendering. It is called with an option object. The function must return a React node.

Nothing found message

The Autocomplete component does not support a nothing found message. It is designed to accept any string as a value, so it does not make sense to show a nothing found message. If you want to limit user input to suggestions, you can use a searchable Select component instead. To learn more about the differences between Autocomplete and Select, check the help center article.

Scrollable dropdown

By default, the options list is wrapped with ScrollArea.Autosize. You can control the dropdown max-height with the maxDropdownHeight prop if you do not change the default settings.

If you want to use native scrollbars, set withScrollArea={false}. Note that in this case, you will need to change the dropdown styles with Styles API.

Fit dropdown to viewport height

Set floatingHeight="viewport" to make the dropdown grow to fill the available vertical space in the viewport. The flip middleware is disabled in this mode – the dropdown always opens in the configured direction and is constrained to the viewport edges instead of flipping to the other side. Useful when working with large option lists:

Group options

Disabled options

When an option is disabled, it cannot be selected and is ignored in keyboard navigation.

Inside Popover

To use Autocomplete inside popover, you need to set withinPortal: false:

Clearable

Set the clearable prop to display the clear button in the right section. The button is not displayed when:

  • The component does not have a value
  • The component is disabled
  • The component is read only

Control dropdown opened state

You can control the dropdown opened state with the dropdownOpened prop. Additionally, you can use onDropdownClose and onDropdownOpen to listen to dropdown opened state changes.

By default, the dropdown is displayed below the input if there is enough space; otherwise it is displayed above the input. You can change this behavior by setting the position and middlewares props, which are passed down to the underlying Popover component.

Example of dropdown that is always displayed above the input:

By default, dropdown animations are disabled. To enable them, you can set transitionProps, which will be passed down to the underlying Transition component.

Input props

Read only

Set readOnly to make the input read only. When readOnly is set, Autocomplete will not show suggestions and will not call the onChange function.

Disabled

Set disabled to disable the input. When disabled is set, users cannot interact with the input and Autocomplete will not show suggestions.

Error state

Success state

Source-backed parameter reference

Implementation signatures and types are generated from the pinned local source. Optional props, native inherited types, union branches and never exclusions are preserved. A forwardRef implementation's ref is a React reference, not an additional business prop.
