Transitions

Animate mounting and unmounting with native Collapse, Fade, Grow, Slide or Zoom.

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

Use case and business boundary

Child refs and lifecycles must remain compatible; respect reduced motion and do not keep hidden heavy engines running.

Native composition and scope

Collapse, Fade, Grow, Slide, Zoom

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.

• Collapse · SimpleCollapse · upstream native demo
• Fade · SimpleFade · upstream native demo
• Grow · SimpleGrow · upstream native demo
• Slide · SimpleSlide · upstream native demo
• Slide relative to a container · SlideFromContainer · upstream native demo
• Zoom · SimpleZoom · upstream native demo

Explicitly unsupported additional examples

These remain in the upstream inventory, not silently skipped or presented as working previews. Additional dependency/framework acceptance is required.

• TransitionGroup · TransitionGroupExample: react-transition-group

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 Switch from '@mui/material/Switch';
import Paper from '@mui/material/Paper';
import Collapse from '@mui/material/Collapse';
import FormControlLabel from '@mui/material/FormControlLabel';

const icon = (
  <Paper sx={{ m: 1, width: 100, height: 100 }} elevation={4}>
    <svg width="100" height="100">
      <Box
        component="polygon"
        points="0,100 50,00, 100,100"
        sx={(theme) => ({
          fill: theme.palette.common.white,
          stroke: theme.palette.divider,
          strokeWidth: 1,
        })}
      />
    </svg>
  </Paper>
);

export default function SimpleCollapse() {
  const [checked, setChecked] = React.useState(false);

  const handleChange = () => {
    setChecked((prev) => !prev);
  };

  return (
    <Box sx={{ height: 300 }}>
      <FormControlLabel
        control={<Switch checked={checked} onChange={handleChange} />}
        label="Show"
      />
      <Box
        sx={{
          '& > :not(style)': {
            display: 'flex',
            justifyContent: 'space-around',
            height: 120,
            width: 250,
          },
        }}
      >
        <div>
          <Collapse in={checked}>{icon}</Collapse>
          <Collapse in={checked} collapsedSize={40}>
            {icon}
          </Collapse>
        </div>
        <div>
          <Box sx={{ width: '50%' }}>
            <Collapse orientation="horizontal" in={checked}>
              {icon}
            </Collapse>
          </Box>
          <Box sx={{ width: '50%' }}>
            <Collapse orientation="horizontal" in={checked} collapsedSize={40}>
              {icon}
            </Collapse>
          </Box>
        </div>
      </Box>
    </Box>
  );
}

Example dependency boundaries

react, @mui/material/Box, @mui/material/Switch, @mui/material/Paper, @mui/material/Collapse, @mui/material/FormControlLabel, @mui/material/Fade, @mui/material/Grow, @mui/material/Slide, @mui/material/Zoom

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.

Collapse

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

Native inheritance: Transition. Parent/DOM props are not fabricated as additional own props.

Fade

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

Native inheritance: Transition. Parent/DOM props are not fabricated as additional own props.

Grow

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

Native inheritance: Transition. Parent/DOM props are not fabricated as additional own props.

Slide

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

Zoom

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

Native inheritance: Transition. Parent/DOM props are not fabricated as additional own props.

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.
