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.
autoFocus	bool	-	If `true`, the `input` element is focused during the first mount.
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.
clearIcon	node	<ClearIcon fontSize="md" />	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.
color	'danger' \| 'neutral' \| 'primary' \| 'success' \| 'warning'	'neutral'	The color of the component. It supports those theme colors that make sense for this component. To learn how to add your own colors, check out Themed components—Extend colors.

error	bool	false	If `true`, the `input` will indicate an error. The prop defaults to the value (`false`) inherited from the parent FormControl component.
filterOptions	func	createFilterOptions()	A function that determines the filtered options to be rendered on search. Signature:`function(options: Array, state: object) => Array` `options` The options to render. `state` The state of the component.
filterSelectedOptions	bool	false	If `true`, hide the selected options from the list box.
forcePopupIcon	'auto' \| bool	'auto'	Force the visibility display of the popup icon.

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). If used in free solo mode, it must accept both the type of the options and a string. Signature:`function(option: Value) => string`
