  return <Slider label="Speed" showLabel defaultValue={1.5} min={0.5} max={2} step={0.25} formatValue={(v) => `${v}×`} />;
}

Centred

origin={0} on a ± range.

Brightness

"use client";

import { Slider } from "@krizaka/ui/slider";

// `origin={0}` on a ±range: the fill starts at the centre.
export default function SliderCentred() {
  return <Slider label="Brightness" showLabel defaultValue={-30} min={-100} max={100} origin={0} formatValue={(v) => `${v > 0 ? "+" : ""}${v} %`} />;
}

Range

Two thumbs, each named.

Price

"use client";

import { Slider } from "@krizaka/ui/slider";

// Two thumbs, each named by `thumbLabels`.
export default function SliderRange() {
  return (
    <Slider<[number, number]>
      label="Price"
      thumbLabels={["Minimum price", "Maximum price"]}
      showLabel
      defaultValue={[10, 60]}

Props

A slider on one value or a range: value/defaultValue + onValueChange, min, max, step.

Prop	Type	Défaut	Description
`label`requis	`string`	—	The accessible name — of the thumb, or of both thumbs of a range — passed translated.
`defaultValue`	`SliderValue`	—	The value at first, uncontrolled: one number, or two for a range.
`formatValue`	`((value: number) => string)`	—	The value as words (aria-valuetext) and as shown: "1.5×", "−12 %", "3 min".
`onValueChange`	`((value: V) => void)`	—	Called on every move, with one number or two.
`onValueCommit`	`((value: V) => void)`	—	Called once the drag or the key press ends.
`origin`	`number`	—	Fills from this value instead of the minimum (a ±range from 0: brightness, balance). One thumb only.
`showLabel`	`boolean`	—	Shows the label and the value above the track. Without it, `label` only names the thumb.
`thumbLabels`	`[string, string]`	—	For a range: each thumb's own name (["Minimum", "Maximum"]), passed translated.
`value`	`SliderValue`	—	One number (a thumb) or two (a range). Controlled with `onValueChange`.

Accessibilité

Radix Slider: each thumb is a slider named by label (or thumbLabels for a range).
formatValue also gives aria-valuetext: the value as it is read.

Clavier

Touches	Action
`Arrow keys`	Move by one step.
`Page Up / Page Down`	Move by a larger step.
`Home / End`	Go to the minimum or the maximum.

Bonnes pratiques

Show the value (showLabel) when it matters, formatted by formatValue.
Choose a step people can reach with the arrows; origin to fill from a centre on a ± range.
