Slider

A draggable input for picking a value or range — volume, price filters, settings — with the neobrutalist borders-and-shadows treatment.

import { Slider } from "@/components/ui/slider"

export function SliderDemo() {

The slider lets users pick a value — or a range between two thumbs — by dragging along a track. Built on the Base UI Slider component and styled to the neobrutalist recipe: thick borders, a hard-shadowed square thumb, and a solid filled range.

Reach for it when:

  • Volume, brightness, playback position — media players and device-style controls where dragging beats typing.
  • Price and range filters — two thumbs give you a min–max filter for search and e-commerce listings.
  • Numeric settings with sane bounds — opacity, border radius, font size; anywhere a bounded number is better shown than typed.

Usage

import { Slider } from "@/components/ui/slider"
<Slider defaultValue={[33]} max={100} step={1} />

Examples

Range

Use an array with two values for a range slider.

import { Slider } from "@/components/ui/slider"

export function SliderRange() {

Multiple Thumbs

Use an array with multiple values for multiple thumbs.

import { Slider } from "@/components/ui/slider"

export function SliderMultiple() {

Vertical

Use orientation="vertical" for a vertical slider.

import { Slider } from "@/components/ui/slider"

export function SliderVertical() {

Controlled

"use client"

import * as React from "react"

Disabled

Use the disabled prop to disable the slider.

import { Slider } from "@/components/ui/slider"

export function SliderDisabled() {

RTL

To enable RTL support in Neobrutalism.com, see the RTL configuration guide.

"use client"

import * as React from "react"

Accessibility

The slider follows the WAI-ARIA Slider pattern: each thumb is a focusable role="slider" element with aria-valuemin, aria-valuemax, and aria-valuenow kept in sync, backed by a hidden input for form submission. A slider has no visible label of its own, so pass aria-label or aria-labelledby — this wrapper forwards both to the thumb, the element screen readers actually announce.

Keyboard interactions:

KeyAction
Tab / Shift + TabMove focus between thumbs and out
ArrowRight / ArrowUpIncrease the value by one step
ArrowLeft / ArrowDownDecrease the value by one step
PageUp / PageDownIncrease / decrease by largeStep (default 10)
Shift + ArrowIncrease / decrease by largeStep
Home / EndJump to the minimum / maximum

In RTL, the horizontal arrow keys follow the reading direction.
