Usage

NumberField renders a spinbutton input with optional increment, decrement, and scrub controls. Wire it up with v-model for two-way binding.

<script setup lang="ts">
  import { NumberField } from '@vuetify/v0'
  import { shallowRef } from 'vue'

  const quantity = shallowRef<number | null>(1)
</script>

<template>
  <div class="flex items-center justify-center">
    <NumberField.Root v-model="quantity" :max="99" :min="0">
      <NumberField.Decrement class="px-3 py-2 border border-divider rounded-l-lg hover:bg-surface-tint disabled:opacity-50">
        &minus;
      </NumberField.Decrement>

      <NumberField.Control class="w-20 text-center border-y border-divider py-2 outline-none bg-transparent" />

      <NumberField.Increment class="px-3 py-2 border border-divider rounded-r-lg hover:bg-surface-tint disabled:opacity-50">
        +
      </NumberField.Increment>
    </NumberField.Root>
  </div>
</template>

Anatomy

vue

<script setup lang="ts">
  import { NumberField } from '@vuetify/v0'
</script>

<template>
  <NumberField.Root>
    <NumberField.Scrub />

    <NumberField.Description />

    <NumberField.Decrement />

    <NumberField.Control />

    <NumberField.Increment />

    <NumberField.Error />

    <NumberField.HiddenInput />
  </NumberField.Root>
</template>

Architecture

Root composes createNumberField which delegates to createInput for field state and createNumeric for math operations. Each sub-component consumes the root context.

Examples

Currency Formatting

Locale-aware currency display using Intl.NumberFormat. The format prop accepts any Intl.NumberFormatOptions, and the Scrub label allows drag-to-adjust the value.

Amount

Tip

Total: $48.30

<template>
  <NumberField.Root :spin-delay="300" :spin-rate="40">
    <NumberField.Decrement>-</NumberField.Decrement>
    <NumberField.Control />
    <NumberField.Increment>+</NumberField.Increment>
  </NumberField.Root>
</template>

Mouse Wheel

Enable value adjustment via scroll wheel when the input is focused:

vue

<template>
  <NumberField.Root v-model="value" wheel>
    <NumberField.Control />
  </NumberField.Root>
</template>

Data Attributes

Style interactive states without slot props:

Attribute	Values	Components
`data-state`	`valid`, `invalid`, `pristine`	Root, Control
`data-dirty`	`true`	Root
`data-focused`	`true`	Root, Control
`data-disabled`	`true`	Root, Control, Increment, Decrement, Scrub
`data-readonly`	`true`	Root, Control, Scrub

Accessibility

NumberField.Control renders with role="spinbutton" and full ARIA attributes per the WAI-ARIA Spinbutton pattern↗.

ARIA Attributes

Attribute	Value	Notes
`role`	`spinbutton`	Applied to Control
`aria-valuenow`	Current value	`undefined` when empty
`aria-valuemin`	Min value	Only when finite
`aria-valuemax`	Max value	Only when finite
`aria-valuetext`	Formatted string	Screen readers announce “$42.00” not “42”
`aria-invalid`	`true`	When validation fails
`aria-label`	Label text	From Root’s `label` prop
`aria-describedby`	Description ID	When Description is mounted
`aria-errormessage`	Error ID	When Error is mounted with messages
`aria-required`	`true`	When Root has `required`

Increment and Decrement buttons use tabindex="-1" to keep them out of the tab sequence — only the Input is focusable.

Key	Action
`ArrowUp`	Increment by one step
`ArrowDown`	Decrement by one step
`Shift+ArrowUp`	Increment by 10 steps
`Shift+ArrowDown`	Decrement by 10 steps
`PageUp`	Increment by leap (default step × 10)
`PageDown`	Decrement by leap (default step × 10)
`Home`	Set to minimum
`End`	Set to maximum
`Enter`	Commit the typed value
