Number Input

<wa-number-input>

Stable

Number inputs let users enter and edit numeric values, with optional stepper buttons for incrementing and decrementing. Use them for quantities, measurements, and other numeric form fields.

<wa-number-input label="Quantity" value="1" style="max-width: 260px;"></wa-number-input>

This component works with standard <form> elements. Please refer to the section on form controls to learn more about form submission and client-side validation.

Labels

Link to This Section

Use the label attribute to give the input an accessible label. For labels that contain HTML, use the label slot instead.

<wa-number-input label="How many items?" style="max-width: 260px;"></wa-number-input>

Hint

Link to This Section

Add descriptive hint to an input with the hint attribute. For hints that contain HTML, use the hint slot instead.

<wa-number-input
  label="Order quantity"
  hint="Enter the number of items you'd like to order"
  style="max-width: 260px;"
></wa-number-input>

Placeholders

Link to This Section

Use the placeholder attribute to add a placeholder.

<wa-number-input placeholder="Enter a number" style="max-width: 260px;"></wa-number-input>

Setting Min, Max, & Step

Link to This Section

Use the min and max attributes to set a minimum and maximum value. Use the step attribute to change the granularity the value must adhere to when using the stepper buttons or arrow keys.

<wa-number-input
  label="Donation amount"
  hint="Amount in dollars (10-100, increments of 5)"
  min="10"
  max="100"
  step="5"
  value="25"
  style="max-width: 260px;"
></wa-number-input>

Appearance

Link to This Section

Use the appearance attribute to change the input's visual appearance.

<wa-number-input label="Outlined" appearance="outlined" value="42" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Filled" appearance="filled" value="42" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input
  label="Filled Outlined"
  appearance="filled-outlined"
  value="42"
  style="max-width: 260px;"
></wa-number-input>

Disabled

Link to This Section

Use the disabled attribute to disable an input.

<wa-number-input label="Disabled" value="100" disabled style="max-width: 260px;"></wa-number-input>

Readonly

Link to This Section

Use the readonly attribute to make the input readonly. The value can still be selected and copied, but it cannot be changed.

<wa-number-input label="Readonly" value="42" readonly style="max-width: 260px;"></wa-number-input>

Sizes

Link to This Section

Use the size attribute to change an input's size.

<wa-number-input label="Extra Small" size="xs" value="5" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Small" size="s" value="10" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Medium" size="m" value="20" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Large" size="l" value="30" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Extra Large" size="xl" value="40" style="max-width: 260px;"></wa-number-input>

Pill

Link to This Section

Use the pill attribute to give inputs rounded edges.

<wa-number-input label="Extra Small Pill" size="xs" pill value="5" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Small Pill" size="s" pill value="10" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Medium Pill" size="m" pill value="20" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Large Pill" size="l" pill value="30" style="max-width: 260px;"></wa-number-input>
<br />
<wa-number-input label="Extra Large Pill" size="xl" pill value="40" style="max-width: 260px;"></wa-number-input>

Without Steppers

Link to This Section

Add the without-steppers attribute to remove the increment/decrement buttons. Users can still modify the value using the keyboard.

<wa-number-input label="No steppers" value="50" without-steppers style="max-width: 260px;"></wa-number-input>

When steppers are hidden, users can still use the arrow keys to increment and decrement the value.

Start & End Decorations

Link to This Section

Use the start and end slots to add presentational elements like <wa-icon> within the input.

<wa-number-input label="Price" value="100" style="max-width: 260px;">
  <wa-icon slot="start" name="dollar-sign" family="utility" variant="semibold"></wa-icon>
</wa-number-input>

<br />

<wa-number-input label="Weight (kg)" value="75" style="max-width: 260px;">
  <wa-icon slot="end" name="bag-shopping" family="utility" variant="semibold"></wa-icon>
</wa-number-input>

Custom Stepper Icons

Link to This Section

Use the increment-icon and decrement-icon slots to customize the stepper button icons.

<wa-number-input label="Custom icons" value="5" style="max-width: 260px;">
  <wa-icon slot="increment-icon" name="plus" family="notdog-duo" variant="solid"></wa-icon>
  <wa-icon slot="decrement-icon" name="minus" family="notdog-duo" variant="solid"></wa-icon>
</wa-number-input>

Customizing Label Position

Link to This Section

Use CSS parts to customize the way form controls are drawn. This example uses CSS grid to position the label to the left of the control, but the possible orientations are nearly endless. The same technique works for inputs, textareas, radio groups, and similar form controls.

<div class="label-on-left">
  <wa-number-input label="Quantity" hint="How many do you need?" value="1"></wa-number-input>
  <wa-number-input label="Price" hint="Cost per unit" value="25"></wa-number-input>
</div>

<style>
  .label-on-left {
    display: grid;
    grid-template-columns: auto minmax(0, 1fr);
    gap: var(--wa-space-l);
    align-items: center;

    wa-number-input {
      grid-column: 1 / -1;
      grid-row-end: span 2;
      display: grid;
      grid-template-columns: subgrid;
      gap: 0 var(--wa-space-l);
      align-items: center;
    }

    ::part(label) {
      text-align: right;
    }

    ::part(hint) {
      grid-column: 2;
    }
  }
</style>

Form Validation

Link to This Section

Use the required attribute to make the field required. Combine with min and max for range validation.

  
  Submit
  Reset

<form class="number-input-validation">
  <wa-number-input
    name="quantity"
    label="Quantity"
    hint="Enter a value between 1 and 10"
    min="1"
    max="10"
    required
    style="max-width: 260px;"
  ></wa-number-input>
  <br />
  <wa-number-input
    name="price"
    label="Price"
    hint="Must be a multiple of 0.25"
    min="0"
    step="0.25"
    required
    style="max-width: 260px;"
  ></wa-number-input>
  <br />
  <wa-button appearance="filled" type="submit" variant="neutral">Submit</wa-button>
  <wa-button appearance="filled" type="reset" variant="neutral">Reset</wa-button>
</form>

<script type="module">
  const form = document.querySelector('.number-input-validation');

  form.addEventListener('submit', event => {
    event.preventDefault();

    // Log data to the console for the demo
    console.log(...new FormData(form));
  });
</script>

Methods

Link to This Section

Learn more about methods.

Name	Description	Arguments
`blur()`	Removes focus from the input.
`focus()`	Sets focus on the input.	`options: FocusOptions`
`formStateRestoreCallback()`	Called when the browser is trying to restore element’s state to state in which case reason is "restore", or when the browser is trying to fulfill autofill on behalf of user in which case reason is "autocomplete". In the case of "restore", state is a string, File, or FormData object previously set as the second argument to setFormValue.	`state: string \| File \| FormData \| null, reason: 'autocomplete' \| 'restore'`
`resetValidity()`	Reset validity is a way of removing manual custom errors and native validation.
`select()`	Selects all the text in the input.
`setCustomValidity()`	Do not use this when creating a "Validator". This is intended for end users of components. We track manually defined custom errors so we don't clear them on accident in our validators.	`message: string`
`stepDown()`	Decrements the value by the step amount.
`stepUp()`	Increments the value by the step amount.
