Props

Props of the native component are also available.

Name	Type	Default	Description
options*	array	-	A list of options that will be shown in the Autocomplete.
renderInput*	func	-	Render the input. Note: The `renderInput` prop must return a `TextField` component or a compatible custom component that correctly forwards `InputProps.ref` and spreads `inputProps`. This ensures proper integration with the Autocomplete's internal logic (e.g., focus management and keyboard navigation). Avoid using components like `DatePicker` or `Select` directly, as they may not forward the required props, leading to runtime errors or unexpected behavior. Signature:`function(params: object) => ReactNode`
autoComplete	bool	false	If `true`, the portion of the selected suggestion that the user hasn't typed, known as the completion string, appears inline after the input cursor in the textbox. The inline completion string is visually highlighted and has a selected state.
autoHighlight	bool	false	If `true`, the first option is automatically highlighted.
autoSelect	bool	false	If `true`, the selected option becomes the value of the input when the Autocomplete loses focus unless the user chooses a different option or changes the character string in the input. When using the `freeSolo` mode, the typed value will be the input value if the Autocomplete loses focus without highlighting an option.
blurOnSelect	'mouse' \| 'touch' \| bool	false	Control if the input should be blurred when an option is selected: `false` the input is not blurred. `true` the input is always blurred. `touch` the input is blurred after a touch event. `mouse` the input is blurred after a mouse event.
ChipProps	object	-	Props applied to the `Chip` element. Deprecated－Use `slotProps.chip` instead. This prop will be removed in a future major release. See Migrating from deprecated APIs for more details.
classes	object	-	Override or extend the styles applied to the component. See CSS classes API below for more details.
clearIcon	node	<ClearIcon fontSize="small" />	The icon to display in place of the default clear icon.
clearOnBlur	bool	!props.freeSolo	If `true`, the input's text is cleared on blur if no value is selected. Set it to `true` if you want to help the user enter a new value. Set it to `false` if you want to help the user resume their search.
clearOnEscape	bool	false	If `true`, clear all values when the user presses escape and the popup is closed.
clearText	string	'Clear'	Override the default text for the clear icon button. For localization purposes, you can use the provided translations.
closeText	string	'Close'	Override the default text for the close popup icon button. For localization purposes, you can use the provided translations.
componentsProps	{ clearIndicator?: object, paper?: object, popper?: object, popupIndicator?: object }	-	The props used for each slot inside. Deprecated－Use the `slotProps` prop instead. This prop will be removed in a future major release. See Migrating from deprecated APIs for more details.
defaultValue	any	props.multiple ? [] : null	The default value. Use when the component is not controlled.
disableClearable	bool	false	If `true`, the input can't be cleared.

fullWidth	bool	false	If `true`, the input will take up the full width of its container.
getLimitTagsText	func	(more) => `+${more}`	The label to display when the tags are truncated (`limitTags`). Signature:`function(more: number) => ReactNode` `more` The number of truncated tags.
getOptionDisabled	func	-	Used to determine the disabled state for a given option. Signature:`function(option: Value) => boolean` `option: Value` The option to test.

getOptionLabel	func	(option) => option.label ?? option	Used to determine the string value for a given option. It's used to fill the input (and the list box options if `renderOption` is not provided).
