InputNumber

Number FieldGitHub
Input numerical values with a customizable range.
This component relies on the @internationalized/number package which provides utilities for formatting and parsing numbers across locales and numbering systems.

Usage

Use the v-model directive to control the value of the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" />
</template>

Use the default-value prop to set the initial value when you do not need to control its state.

<template>
  <UInputNumber :default-value="5" />
</template>

Min / Max

Use the min and max props to set the minimum and maximum values of the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" :min="0" :max="10" />
</template>

Step

Use the step prop to set the step value of the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" :step="2" />
</template>

Orientation

Use the orientation prop to change the orientation of the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" orientation="vertical" />
</template>

Placeholder

Use the placeholder prop to set a placeholder text.

<template>
  <UInputNumber placeholder="Enter a number" />
</template>

Color

Use the color prop to change the ring color when the InputNumber is focused.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" color="neutral" highlight />
</template>

Variant

Use the variant prop to change the variant of the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" variant="subtle" color="neutral" />
</template>

Size

Use the size prop to change the size of the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" size="xl" />
</template>

Disabled

Use the disabled prop to disable the InputNumber.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value" disabled />
</template>

Increment / Decrement

Use the increment and decrement props to customize the increment and decrement buttons with any Button props. Defaults to { variant: 'link' }.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber
    v-model="value"
    :increment="{
      color: 'neutral',
      variant: 'solid',
      size: 'xs'
    }"
    :decrement="{
      color: 'neutral',
      variant: 'solid',
      size: 'xs'
    }"
  />
</template>

Increment / Decrement Icons

Use the increment-icon and decrement-icon props to customize the buttons Icon. Defaults to i-lucide-plus / i-lucide-minus.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber
    v-model="value"
    increment-icon="i-lucide-arrow-right"
    decrement-icon="i-lucide-arrow-left"
  />
</template>

Examples

With decimal format

Use the format-options prop to customize the format of the value.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber
    v-model="value"
    :format-options="{
      signDisplay: 'exceptZero',
      minimumFractionDigits: 1
    }"
  />
</template>

With percentage format

Use the format-options prop with style: 'percent' to customize the format of the value.

<script setup lang="ts">
const value = ref(0.05)
</script>

<template>
  <UInputNumber
    v-model="value"
    :step="0.01"
    :format-options="{
      style: 'percent'
    }"
  />
</template>

With currency format

Use the format-options prop with style: 'currency' to customize the format of the value.

<script setup lang="ts">
const value = ref(1500)
</script>

<template>
  <UInputNumber
    v-model="value"
    :format-options="{
      style: 'currency',
      currency: 'EUR',
      currencyDisplay: 'code',
      currencySign: 'accounting'
    }"
  />
</template>

Within a FormField

You can use the InputNumber within a FormField component to display a label, help text, required indicator, etc.

Specify number of attempts

<script setup lang="ts">
const retries = ref(0)
</script>

<template>
  <UFormField label="Retries" help="Specify number of attempts" required>
    <UInputNumber v-model="retries" placeholder="Enter retries" />
  </UFormField>
</template>

With slots

Use the #increment and #decrement slots to customize the buttons.

<script setup lang="ts">
const value = ref(5)
</script>

<template>
  <UInputNumber v-model="value">
    <template #decrement>
      <UButton size="xs" icon="i-lucide-minus" />
    </template>

    <template #increment>
      <UButton size="xs" icon="i-lucide-plus" />
    </template>
  </UInputNumber>
</template>
