Number input

Number Input

A field that allows user input of numeric values.

You can explore the number-input component in the following curated examples.

Slider with Number Input

Render a Slider with a Tooltip that shows the current value of the Slider.

Anatomy

To set up the number input correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the NumberInput component in your project. Let's take a look at the most basic example:

import { NumberInput } from '@ark-ui/solid/number-input'

export const Basic = () => (
  <NumberInput.Root>
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Setting a minimum and maximum value

Pass the min prop or max prop to set an upper and lower limit for the input. By default, the input will restrict the value to stay within the specified range.

import { NumberInput } from '@ark-ui/solid/number-input'

export const MinMax = () => (
  <NumberInput.Root min={0} max={10}>
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Adjusting the precision of the value

In some cases, you might need the value to be rounded to specific decimal points. Set the formatOptions and provide Intl.NumberFormatOptions such as maximumFractionDigits or minimumFractionDigits.

import { NumberInput } from '@ark-ui/solid/number-input'

export const FractionDigits = () => (
  <NumberInput.Root
    formatOptions={{ minimumFractionDigits: 2, maximumFractionDigits: 4 }}
    value="1.00"
  >
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Scrubbing the input value

The NumberInput supports the scrubber interaction pattern. To use this pattern, render the NumberInput.Scrubber component. It uses the Pointer lock API and tracks the pointer movement. It also renders a virtual cursor which mimics the real cursor's pointer.

import { NumberInput } from '@ark-ui/solid/number-input'

export const Scrubber = () => (
  <NumberInput.Root>
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Using the mouse wheel to change value

The NumberInput exposes a way to increment/decrement the value using the mouse wheel event. To activate this, set the allowMouseWheel prop to true.

import { NumberInput } from '@ark-ui/solid/number-input'

export const MouseWheel = () => (
  <NumberInput.Root allowMouseWheel>
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Clamp value when user blurs the input

In most cases, users can type custom values in the input field. If the typed value is greater than the max, the value is reset to max when the user blur out of the input.

To disable this behavior, pass clampValueOnBlur and set to false.

import { NumberInput } from '@ark-ui/solid/number-input'

export const NoClamp = () => (
  <NumberInput.Root clampValueOnBlur={false}>
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Usage within forms

To use the number input within forms, set the name prop.

import { NumberInput } from '@ark-ui/solid/number-input'

export const FormUsage = () => (
  <NumberInput.Root name="quantity">
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Format and parse value

To apply custom formatting to the input's value, set the formatOptions and provide Intl.NumberFormatOptions such as style and currency.

import { NumberInput } from '@ark-ui/solid/number-input'

export const Formatted = () => (
  <NumberInput.Root
    formatOptions={{
      style: 'currency',
      currency: 'USD',
    }}
  >
    <NumberInput.Scrubber />
    <NumberInput.Label>Label</NumberInput.Label>
    <NumberInput.Input />
    <NumberInput.Control>
      <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
      <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
    </NumberInput.Control>
  </NumberInput.Root>
)

Using the Field Component

The Field component helps manage form-related state and accessibility attributes of a number input. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility.

import { Field } from '@ark-ui/solid/field'
import { NumberInput } from '@ark-ui/solid/number-input'

export const WithField = (props: Field.RootProps) => (
  <Field.Root {...props}>
    <NumberInput.Root>
      <NumberInput.Label>Label</NumberInput.Label>
      <NumberInput.Input />
      <NumberInput.Control>
        <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
        <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
      </NumberInput.Control>
    </NumberInput.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
)

Using the Root Provider

The RootProvider component provides a context for the number-input. It accepts the value of the useNumber-input hook. You can leverage it to access the component state and methods from outside the number-input.

import { NumberInput, useNumberInput } from '@ark-ui/solid/number-input'

export const RootProvider = () => {
  const numberInput = useNumberInput()

  return (
    <>
      <button onClick={() => numberInput().focus()}>Focus</button>

      <NumberInput.RootProvider value={numberInput}>
        <NumberInput.Label>Label</NumberInput.Label>
        <NumberInput.Input />
        <NumberInput.Control>
          <NumberInput.DecrementTrigger>-1</NumberInput.DecrementTrigger>
          <NumberInput.IncrementTrigger>+1</NumberInput.IncrementTrigger>
        </NumberInput.Control>
      </NumberInput.RootProvider>
    </>
  )
}

If you're using the RootProvider component, you don't need to use the Root component.
