Number Input

The number input component provides a structured way for users to input numerical data with built-in validation and controls. It combines a text input field with stepper buttons and can include unit selection functionality for measurements, currency, or other quantifiable values.

import {NumberInput} from "@qualcomm-ui/react/number-input"

Examples

Simple

The simple API bundles all subcomponents together into a single component.

Brand

Label

<NumberInput className="w-72" label="Label" placeholder="Enter a number" />

Composite

The composite pattern provides full control over the component's elements by composing individual subcomponents.

Brand

Label

<NumberInput.Root className="w-72">
  <NumberInput.Label>Label</NumberInput.Label>
  <NumberInput.InputGroup>
    <NumberInput.Input placeholder="Enter a number" />
    <NumberInput.Control />
    <NumberInput.ErrorIndicator />
  </NumberInput.InputGroup>
  <NumberInput.ErrorText>Error</NumberInput.ErrorText>
</NumberInput.Root>

Min and Max values

Pass the min and max props to the root component to set the minimum and maximum values of the number input.

If the value entered is less than min or greater than max, it will be clamped to the nearest boundary on blur or enter.

Brand

<NumberInput
  aria-label="input min-max demo"
  className="w-72"
  defaultValue="5"
  max={10}
  min={5}
/>

Step interval

Pass the step prop to the root component to set the increment or decrement step interval.

Brand

<NumberInput
  aria-label="Steps demo"
  className="w-72"
  placeholder="Enter a number"
  step={3}
/>

States

The following shows how the TextInput component appears in each interactive state.

Brand

Disabled

Read only

Required

Invalid

<NumberInput disabled label="Disabled" placeholder="Disabled" />
<NumberInput label="Read only" placeholder="Read only" readOnly />
<NumberInput label="Required" placeholder="Required" required />
<NumberInput
  errorText="Invalid"
  invalid
  label="Invalid"
  placeholder="Invalid"
/>

Controlled Value

Use the value, onValueChange and defaultValue props to control the value of the input field. These props follow our controlled state pattern.

Brand

Controlled Value

import {type ReactElement, useState} from "react"

import {NumberInput} from "@qualcomm-ui/react/number-input"

export function NumberInputControlledDemo(): ReactElement {
  const [value, setValue] = useState<string>("")
  return (
    <NumberInput
      className="w-72"
      label="Controlled Value"
      onValueChange={({value}) => setValue(value)}
      placeholder="Placeholder"
      value={value}
    />
  )
}

Sizes

Customize size using the size prop. The default size is md.

Brand

<NumberInput
  aria-label="sm demo"
  className="w-56"
  placeholder="sm"
  size="sm"
  startIcon={Sigma}
/>
<NumberInput
  aria-label="md demo"
  className="w-64"
  placeholder="md"
  startIcon={Sigma}
/>
<NumberInput
  aria-label="lg demo"
  className="w-72"
  placeholder="lg"
  size="lg"
  startIcon={Sigma}
/>

Error Text and Indicator

Error messages are displayed using two props:

invalid
errorText (or the NumberInput.ErrorText component when using the composite API)

The error text and indicator will only render when invalid is true.

Brand

Label

You must enter a value

<NumberInput
  className="w-72"
  errorText="You must enter a value"
  invalid={!value}
  label="Label"
  onValueChange={({value}) => setValue(value)}
  placeholder="Enter a value"
  value={value}
/>
