Slider

Choose scalar or range values with native marks and accessible labels.

This guide covers Material UI Core with the default Emotion engine; extensions and additional demos are explicitly classified.

Use case and business boundary

Slider may return number or number[]; distinguish live change from committed change and map nonlinear scales explicitly.

Native composition and scope

Slider

Preserve native Material UI composition and types; do not substitute JGuang UI/Base UI/Radix APIs. Example entries are not extra components.

Native installation and initialization

npm install @mui/material@9.4.0 @emotion/react@11.14.0 @emotion/styled@11.14.1

Use native npm and Emotion, not an invented JGuang UI Registry URL. Place examples inside native ThemeProvider; choose CssBaseline or ScopedCssBaseline for the project. Inspect React, existing providers, lockfile and SSR first. Never overwrite files or conceal peer conflicts. This batch verified React 19.2.8; React 18 and below require matching react-is. See the included bilingual setup guide.

Practical native parameters

These selected parameters are not a flattened universal API. Preserve the native declaring owner, slot structure, nullable values and generics.

Runnable native examples

Machine keys select example entries, not universal variant props. Native demo JSX/data stay unchanged; JGuang-authored acceptance fixtures are explicitly labelled.

Actual usage example

Unmodified pinned native demo; copy its required local helper files together.

import * as React from 'react';
import Box from '@mui/material/Box';
import Stack from '@mui/material/Stack';
import Slider from '@mui/material/Slider';
import VolumeDown from '@mui/icons-material/VolumeDown';
import VolumeUp from '@mui/icons-material/VolumeUp';

export default function ContinuousSlider() {
  const [value, setValue] = React.useState<number>(30);

  const handleChange = (event: Event, newValue: number) => {
    setValue(newValue);
  };

  return (
    <Box sx={{ width: 200 }}>
      <Stack spacing={2} direction="row" sx={{ alignItems: 'center', mb: 1 }}>
        <VolumeDown />
        <Slider aria-label="Volume" value={value} onChange={handleChange} />
        <VolumeUp />
      </Stack>
      <Slider disabled defaultValue={30} aria-label="Disabled slider" />
    </Box>
  );
}

Example dependency boundaries

react, @mui/material/Box, @mui/material/Stack, @mui/material/Slider, @mui/icons-material/VolumeDown, @mui/icons-material/VolumeUp, @mui/material/styles, @mui/material/Grid, @mui/material/Typography, @mui/material/Input, @mui/material/Tooltip, @mui/material/IconButton, @mui/icons-material/PauseRounded, @mui/icons-material/PlayArrowRounded, @mui/icons-material/FastForwardRounded, @mui/icons-material/FastRewindRounded, @mui/icons-material/VolumeUpRounded, @mui/icons-material/VolumeDownRounded

Direct Icons/System/Utils example imports require their matching 9.4.0 packages. Relative data/helpers are part of the example closure, not extra components. Remote images and simulated operations do not supply a backend.

Pinned upstream API metadata reference

These tables retain the upstream metadata, not a newly inferred generic type system. Conditional generics, inherited props and callback details are defined by the source declarations below. Theme defaults may override metadata defaults.

Slider

import Slider from '@mui/material/Slider';
import { Slider } from '@mui/material';

Native source declarations

Declarations/imports are extracted from pinned source without flattening unions or external inheritance. Original English comments/types are source reference, not a claim of translated upstream prose. Shared types stay in their native packages.

Post-install acceptance

Run strict types, production build and real interactions. Check keyboard labels/focus, disabled/error/read-only semantics where natively supported, both themes, narrow screens and reduced motion. Verify callbacks against the real host data; do not declare installation complete from copying a prompt. Initialization fixtures also require server HTML and warning-free hydration.
