⚙️ Configuration

NumericStepper supports the following props:

Prop	Type	Default value	Description
minimumValue	number	0	The minimum value.
maximumValue	number	Number.MAX_SAFE_INTEGER	The maximum value.
stepValue	number	1	The step increment value.
initialValue	number	minimumValue	The initial value.
onChange	Function	undefined	The callback invoked when the value changes.
size	string	sm	The size of the numeric stepper. There are 3 available sizes:sm — 185x74pxmd — 277.5x111pxlg — 370x148px
inactiveTrackColor	string	#2b2b2b	The color of the track while the thumb is not being horizontally dragged.
activeTrackColor	string	#1f1f1f	The color of the track while the thumb is being horizontally dragged and is at the maximum trackable distance from the track's center.
hoverButtonColor	string	transparent	The color of the decrement/increment button in a hover state.
activeButtonColor	string	#ececec	The color of the decrement/increment button in an active state.
inactiveIconColor	string	#858585	The color of the decrement/increment button icon in an inactive state.
hoverIconColor	string	#ffffff	The color of the decrement/increment button icon in a hover state.
activeIconColor	string	#000000	The color of the decrement/increment button icon in an active state.
disabledIconColor	string	#383838	The color of the decrement/increment button icon in a disabled state.
thumbColor	string	#444444	The color of the thumb.
thumbLabelColor	string	#ffffff	The color of the thumb's label.
thumbShadowAnimationOnTrackHoverEnabled	boolean	true	If true, the thumb's shadow will animate when hovering over the track.
focusRingColor	string	#ececec	The color of the focus ring of the interactive elements.

In order to customise the thumb's font settings, we can use CSS, like so:

[data-testid='numeric-stepper-thumb'] {
  font-family: 'Times New Roman', Times, serif;
  font-style: italic;
  font-weight: 800;
}

♿️ Accessibility

In order to comply with the web accessibility standards, we must make use of the decrementButtonAriaLabel and incrementButtonAriaLabel props, like so:

function AccessibleExample() {
  return (
    <NumericStepper
      decrementButtonAriaLabel="Decrement"
      incrementButtonAriaLabel="Increment"
    />
  );
}

Also, we can use a thumbAriaLabel prop to provide a description for the value rendered inside a thumb, like so:

function EnhancedThumbAccessibilityExample() {
  const [value, setValue] = useState(0);
  return (
    <NumericStepper
      thumbAriaLabel={`${value} items`}
      onChange={(value) => {
        setValue(value);
      }}
    />
  );
}
