Props

Props of the OutlinedInput component are also available.

Name	Type	Default	Description
autoWidth	bool	false	If `true`, the width of the popover will automatically be set according to the items inside the menu, otherwise it will be at least the width of the select input.
children	node		The option elements to populate the select with. Can be some `MenuItem` when `native` is false and `option` when `native` is true. ⚠️The `MenuItem` elements must be direct descendants when `native` is false.
classes	object	{}	Override or extend the styles applied to the component. See CSS API below for more details.
defaultOpen	bool	false	If `true`, the component is initially open. Use when the component open state is not controlled (i.e. the `open` prop is not defined). You can only use it when the `native` prop is `false` (default).
defaultValue	any		The default value. Use when the component is not controlled.
displayEmpty	bool	false	If `true`, a value is displayed even if no items are selected. In order to display a meaningful value, a function can be passed to the `renderValue` prop which returns the value to be displayed when no items are selected. ⚠️ When using this prop, make sure the label doesn't overlap with the empty displayed value. The label should either be hidden or forced to a shrunk state.
IconComponent	elementType	ArrowDropDownIcon	The icon that displays the arrow.
id	string		The `id` of the wrapper element or the `select` element when `native`.
input	element		An `Input` element; does not have to be a material-ui specific `Input`.
inputProps	object		Attributes applied to the `input` element. When `native` is `true`, the attributes are applied on the `select` element.
label	node		See OutlinedInput#label
labelId	string		The ID of an element that acts as an additional label. The Select will be labelled by the additional label and the selected value.
MenuProps	object		Props applied to the `Menu` element.
multiple	bool	false	If `true`, `value` must be an array and the menu will support multiple selections.
native	bool	false	If `true`, the component uses a native `select` element.
onChange	func		Callback fired when a menu item is selected. Signature:`function(event: SelectChangeEvent, child?: object) => void` `event` The event source of the callback. You can pull out the new value by accessing `event.target.value` (any). Warning: This is a generic event, not a change event, unless the change event is caused by browser autofill. `child` The react element that was selected when `native` is `false` (default).
onClose	func		Callback fired when the component requests to be closed. Use it in either controlled (see the `open` prop), or uncontrolled mode (to detect when the Select collapses). Signature:`function(event: object) => void` `event` The event source of the callback.
onOpen	func		Callback fired when the component requests to be opened. Use it in either controlled (see the `open` prop), or uncontrolled mode (to detect when the Select expands). Signature:`function(event: object) => void` `event` The event source of the callback.
open	bool		If `true`, the component is shown. You can only use it when the `native` prop is `false` (default).
renderValue	func		Render the selected value. You can only use it when the `native` prop is `false` (default). Signature:`function(value: any) => ReactNode` `value` The `value` provided to the component.
SelectDisplayProps	object		Props applied to the clickable div element.
sx	Array<func \| object \| bool> \| func \| object		The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
value	'' \| any		The `input` value. Providing an empty string will select no options. Set to an empty string `''` if you don't want any of the available options to be selected. If the value is an object it must have reference equality with the option in order to be selected. If the value is not an object, the string representation must match with the string representation of the option in order to be selected.
variant	'filled' \| 'outlined' \| 'standard'	'outlined'	The variant to use.

The ref is forwarded to the root element.
