Autocomplete
The autocomplete is a normal text input enhanced by a panel of suggested options.
The widget is useful for setting the value of a single-line textbox in one of two types of scenarios:
- The value for the textbox must be chosen from a predefined set of allowed values, e.g., a location field must contain a valid location name: combo box.
- The textbox may contain any arbitrary value, but it is advantageous to suggest possible values to the user, e.g., a search field may suggest similar or previous searches to save the user time: free solo.
Combo box
The value must be chosen from a predefined set of allowed values.
<Autocomplete
id="combo-box-demo"
options={top100Films}
getOptionLabel={option => option.title}
style={{ width: 300 }}
renderInput={params => (
<TextField {...params} label="Combo box" variant="outlined" fullWidth />
)}
/>
<Autocomplete
id="grouped-demo"
options={options.sort((a, b) => -b.firstLetter.localeCompare(a.firstLetter))}
groupBy={option => option.firstLetter}
getOptionLabel={option => option.title}
style={{ width: 300 }}
renderInput={params => (
<TextField {...params} label="With categories" variant="outlined" fullWidth />
)}
/>
<Autocomplete
id="disabled-options-demo"
options={timeSlots}
getOptionDisabled={option => option === timeSlots[0] || option === timeSlots[2]}
style={{ width: 300 }}
renderInput={params => (
<TextField {...params} label="Disabled options" variant="outlined" fullWidth />
)}
/>
useAutocomplete
For advanced customization use cases, we expose a useAutocomplete()
hook.
It accepts almost the same options as the Autocomplete component minus all the props
related to the rendering of JSX.
The Autocomplete component uses this hook internally.
import useAutocomplete from '@material-ui/lab/useAutocomplete';
Head to the Customized Autocomplete section for a customization example with the Autocomplete
component instead of the hook.
Asynchronous requests
For this demo, we need to load the Google Maps JavaScript API.
⚠️ Before you can start using the Google Maps JavaScript API, you must sign up and create a billing account.
Multiple values
Also known as tags, the user is allowed to enter more than one value.
Fixed options
In the event that you need to lock certain tag so that they can't be removed in the interface, you can set the chips disabled.

hook instead of the component.
Highlights
The following demo relies on autosuggest-highlight, a small (1 kB) utility for highlighting text in autosuggest and autocomplete components.
Custom filter
The component exposes a factory to create a filter method that can provided to the filerOption
prop.
You can use it to change the default option filter behavior.
import { createFilterOptions } from '@material-ui/lab/Autocomplete';
It supports the following options:
config
(Object [optional]):config.ignoreAccents
(Boolean [optional]): Defaults totrue
. Remove diacritics.config.ignoreCase
(Boolean [optional]): Defaults totrue
. Lowercase everything.config.matchFrom
('any' | 'start' [optional]): Defaults to'any'
.config.stringify
(Func [optional]): Defaults toJSON.stringify
.config.trim
(Boolean [optional]): Defaults tofalse
. Remove trailing spaces.
In the following demo, the options need to start with the query prefix:
const filterOptions = createFilterOptions({
matchFrom: 'start',
stringify: option => option.title,
});
<Autocomplete filterOptions={filterOptions} />
Advanced
For richer filtering mechanisms, like fuzzy matching, it's recommended to look at match-sorter. For instance:
import matchSorter from 'match-sorter';
const filterOptions = (options, { inputValue }) =>
matchSorter(options, inputValue);
<Autocomplete filterOptions={filterOptions} />
Virtualization
Search within 10,000 randomly generated options. The list is virtualized thanks to react-window.
<Autocomplete
id="virtualize-demo"
style={{ width: 300 }}
disableListWrap
classes={classes}
ListboxComponent={ListboxComponent}
renderGroup={renderGroup}
options={OPTIONS}
groupBy={option => option[0].toUpperCase()}
renderInput={params => (
<TextField {...params} variant="outlined" label="10,000 options" fullWidth />
)}
renderOption={option => <Typography noWrap>{option}</Typography>}
/>
Limitations
iOS VoiceOver
VoiceOver on iOS Safari doesn't support the aria-owns
attribute very well.
You can work around the issue with the disablePortal
prop.
Accessibility
(WAI-ARIA: https://www.w3.org/TR/wai-aria-practices/#combobox)
We encourage the usage of a label for the textbox. The component implements the WAI-ARIA authoring practices.
