MUI Core Components Reference

Input Components

TextField

The most common form input. Wraps FormControl, InputLabel, OutlinedInput/FilledInput/Input, and FormHelperText in one component.

import TextField from '@mui/material/TextField';
import InputAdornment from '@mui/material/InputAdornment';

// Standard usage
<TextField
  label="Email address"
  type="email"
  variant="outlined"          // 'outlined' | 'filled' | 'standard'
  size="small"                // 'small' | 'medium'
  fullWidth
  required
  value={email}
  onChange={(e) => setEmail(e.target.value)}
  error={!!emailError}
  helperText={emailError || 'We will never share your email'}
  InputProps={{
    startAdornment: <InputAdornment position="start"><EmailIcon /></InputAdornment>,
  }}
  inputProps={{ maxLength: 100, 'aria-label': 'email address' }}
/>

// Multiline / textarea
<TextField
  label="Description"
  multiline
  rows={4}
  // or: minRows={2} maxRows={8} for auto-grow
  fullWidth
/>

Autocomplete

Combines a text input with a dropdown for both free-form and constrained selection.

import Autocomplete from '@mui/material/Autocomplete';
import Chip from '@mui/material/Chip';
import CircularProgress from '@mui/material/CircularProgress';

// Static options
<Autocomplete
  options={countries}
  getOptionLabel={(option) => option.label}
  isOptionEqualToValue={(option, value) => option.code === value.code}
  value={selectedCountry}
  onChange={(_, newValue) => setSelectedCountry(newValue)}
  renderInput={(params) => (
    <TextField {...params} label="Country" />
  )}
/>

// Multiple selection with chips
<Autocomplete
  multiple
  options={tags}
  value={selectedTags}
  onChange={(_, newValue) => setSelectedTags(newValue)}
  renderTags={(value, getTagProps) =>
    value.map((option, index) => (
      <Chip label={option} {...getTagProps({ index })} key={option} />
    ))
  }
  renderInput={(params) => (
    <TextField {...params} label="Tags" placeholder="Add tag" />
  )}
/>

// Async / server-side options
const [open, setOpen] = React.useState(false);
const [options, setOptions] = React.useState([]);
const [loading, setLoading] = React.useState(false);

<Autocomplete
  open={open}
  onOpen={() => { setOpen(true); fetchOptions(); }}
  onClose={() => setOpen(false)}
  options={options}
  loading={loading}
  renderInput={(params) => (
    <TextField
      {...params}
      label="Search users"
      InputProps={{
        ...params.InputProps,
        endAdornment: (
          <>
            {loading && <CircularProgress size={20} />}
            {params.InputProps.endAdornment}
          </>
        ),
      }}
    />
  )}
/>

Utility Components

ClickAwayListener

Detects clicks outside the wrapped element — essential for custom dropdowns and popovers.

import ClickAwayListener from '@mui/material/ClickAwayListener';

<ClickAwayListener onClickAway={handleClose}>
  <Box sx={{ position: 'relative' }}>
    <Button onClick={toggleOpen}>Menu</Button>
    {open && (
      <Paper sx={{ position: 'absolute', top: '100%', zIndex: 1, width: 200 }}>
        <MenuItem onClick={handleClose}>Option 1</MenuItem>
        <MenuItem onClick={handleClose}>Option 2</MenuItem>
      </Paper>
    )}
  </Box>
</ClickAwayListener>

Portal

Renders children into document.body or a custom container.

import Portal from '@mui/material/Portal';

<Portal>
  <Box sx={{ position: 'fixed', bottom: 16, right: 16, zIndex: 'tooltip' }}>
    <Fab color="primary"><AddIcon /></Fab>
  </Box>
</Portal>

NoSsr — Client-Only Rendering

import NoSsr from '@mui/material/NoSsr';

<NoSsr fallback={<Skeleton variant="rectangular" height={300} />}>
  <MapComponent /> {/* Depends on window — fails on server */}
</NoSsr>

useMediaQuery — Responsive Conditional Rendering

import useMediaQuery from '@mui/material/useMediaQuery';
import { useTheme } from '@mui/material/styles';

function ResponsiveNav() {
  const theme = useTheme();
  const isMobile = useMediaQuery(theme.breakpoints.down('md'));

  return isMobile ? <MobileBottomNav /> : <DesktopSidebar />;
}

// Without theme — raw media query string
const prefersDark = useMediaQuery('(prefers-color-scheme: dark)');

// With SSR safety — avoid hydration mismatch
const isDesktop = useMediaQuery(theme.breakpoints.up('lg'), {
  noSsr: true,                    // skip server render for this query
  defaultMatches: true,           // assume true on server
  // or: ssrMatchMedia for custom server-side matching
});

---

Component Prop (Polymorphic Rendering)

Most MUI components accept component to change the rendered HTML element or use a router link:

import { Link as RouterLink } from 'react-router-dom';

// Button as router link
<Button component={RouterLink} to="/dashboard" variant="contained">
  Dashboard
</Button>

// ListItemButton as router link
<ListItemButton component={RouterLink} to="/settings">
  <ListItemIcon><SettingsIcon /></ListItemIcon>
  <ListItemText primary="Settings" />
</ListItemButton>

// Typography as a label
<Typography component="label" htmlFor="email-input" variant="body2">
  Email Address
</Typography>

// Card as semantic article
<Card component="article">
  <CardContent>...</CardContent>
</Card>

// Box as section with semantic HTML
<Box component="section" aria-labelledby="section-title">
  <Typography id="section-title" variant="h2">Title</Typography>
</Box>

---

Global Configuration via Theme defaultProps

Set defaults for every instance of a component across the app:

const theme = createTheme({
  components: {
    MuiButton: {
      defaultProps: {
        variant: 'contained',
        disableElevation: true,
        size: 'medium',
      },
    },
    MuiTextField: {
      defaultProps: {
        variant: 'outlined',
        size: 'small',
        fullWidth: true,
      },
    },
    MuiTooltip: {
      defaultProps: {
        arrow: true,
        enterDelay: 500,
      },
    },
    MuiAlert: {
      defaultProps: {
        variant: 'filled',
      },
    },
    MuiChip: {
      defaultProps: {
        size: 'small',
      },
    },
  },
});

Now <Button>Save</Button> renders as contained by default — no need to repeat variant="contained" everywhere.
