Number Input

The Number Input component provides users with a field for integer values, and buttons to increment or decrement the value.

NumberInput API

Import

import NumberInput from '@mui/base/Unstable_NumberInput';
// or
import { Unstable_NumberInput as NumberInput } from '@mui/base';

Props

Props of the native component are also available.

defaultValue

The default value. Use when the component is not controlled.

Type:

any

disabled

If true, the component is disabled. The prop defaults to the value (false) inherited from the parent FormControl component.

Type:

bool

error

If true, the input will indicate an error by setting the aria-invalid attribute on the input and the Mui-error class on the root element.

Type:

bool

The id of the input element.

Type:

string

max

The maximum value.

Type:

number

min

The minimum value.

Type:

number

onChange

Callback fired after the value is clamped and changes - when the input is blurred or when the stepper buttons are triggered. Called with undefined when the value is unset.

Type:

func

Signature:

function(event: React.FocusEvent | React.PointerEvent | React.KeyboardEvent, value: number | undefined) => void

event The event source of the callback
value The new value of the component

onInputChange

Callback fired when the input value changes after each keypress, before clamping is applied. Note that event.target.value may contain values that fall outside of min and max or are otherwise "invalid".

Type:

func

Signature:

function(event: React.ChangeEvent) => void

event The event source of the callback.

readOnly

If true, the input element becomes read-only. The stepper buttons remain active, with the addition that they are now keyboard focusable.

Type:

bool

Default:

false

required

If true, the input element is required. The prop defaults to the value (false) inherited from the parent FormControl component.

Type:

bool

shiftMultiplier

Multiplier applied to step if the shift key is held while incrementing or decrementing the value. Defaults to 10.

Type:

number

slotProps

The props used for each slot inside the NumberInput.

Type:

{ decrementButton?: func | object, incrementButton?: func | object, input?: func | object, root?: func | object }

Default:

{}

slots

The components used for each slot inside the InputBase. Either a string to use a HTML element or a component.

Type:

{ decrementButton?: elementType, incrementButton?: elementType, input?: elementType, root?: elementType }

Default:

{}

step

The amount that the value changes on each increment or decrement.

Type:

number

value

The current value. Use when the component is controlled.

Type:

any

The ref is forwarded to the root element.
