Component name

The name MuiSelect can be used when providing default props or style overrides in the theme.

Props

Name	Type	Default	Description

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.

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: object, 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. child: The react element that was selected when `native` is `false` (default).

onOpen	func		Callback fired when the component requests to be opened. Use in controlled mode (see open). Signature: `function(event: object) => void` event: The event source of the callback.
open	bool	false	If `true`, the component is shown. You can only use it when the `native` prop is `false` (default).

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.
Any other props supplied will be provided to the root element (OutlinedInput).
