Text Field

Text Fields let users enter and edit text.

Text fields allow users to enter text into a UI. They typically appear in forms and dialogs.

Basic TextField

The TextField wrapper component is a complete form control including a label, input, and help text. It comes with three variants: outlined (default), filled, and standard.

Form props

Standard form attributes are supported e.g. required, disabled, type, etc. as well as a helperText which is used to give context about a field's input, such as how the input will be used.

Validation

The error prop toggles the error state. The helperText prop can then be used to provide feedback to the user about the error.

Incorrect entry.

Multiline

The multiline prop transforms the text field into a TextareaAutosize element. Unless the rows prop is set, the height of the text field dynamically matches its content (using TextareaAutosize). You can use the minRows and maxRows props to bound it.

Select

The select prop makes the text field use the Select component internally.

Icons

There are multiple ways to display an icon with a text field.

Input Adornments

The main way is with an InputAdornment. This can be used to add a prefix, a suffix, or an action to an input. For instance, you can use an icon button to hide or reveal the password.

Sizes

Fancy smaller inputs? Use the size prop.

The filled variant input height can be further reduced by rendering the label outside of it.

Margin

The margin prop can be used to alter the vertical spacing of the text field. Using none (default) doesn't apply margins to the FormControl whereas dense and normal do.

Full width

fullWidth can be used to make the input take up the full width of its container.

Uncontrolled vs. Controlled

The component can be controlled or uncontrolled.

Components

TextField is composed of smaller components ( FormControl, Input, FilledInput, InputLabel, OutlinedInput, and FormHelperText ) that you can leverage directly to significantly customize your form inputs.

You might also have noticed that some native HTML input properties are missing from the TextField component. This is on purpose. The component takes care of the most used properties. Then, it's up to the user to use the underlying component shown in the following demo. Still, you can use inputProps (and InputProps, InputLabelProps properties) if you want to avoid some boilerplate.

Color

The color prop changes the highlight color of the text field when focused.

Customization

Here are some examples of customizing the component. You can learn more about this in the overrides documentation page.

Using the styled API

Using the theme style overrides API

Use the styleOverrides key to change any style injected by Material UI into the DOM. See the theme style overrides documentation for further details.

Press Enter to start editing

Customization does not stop at CSS. You can use composition to build custom components and give your app a unique feel. Below is an example using the InputBase component, inspired by Google Maps.


🎨 If you are looking for inspiration, you can check MUI Treasury's customization examples.

useFormControl

For advanced customization use cases, a useFormControl() hook is exposed. This hook returns the context value of the parent FormControl component.

API

import { useFormControl } from '@mui/material/FormControl';

Returns

value (object):

  • value.adornedStart (bool): Indicate whether the child Input or Select component has a start adornment.
  • value.setAdornedStart (func): Setter function for adornedStart state value.
  • value.color (string): The theme color is being used, inherited from FormControl color prop .
  • value.disabled (bool): Indicate whether the component is being displayed in a disabled state, inherited from FormControl disabled prop.
  • value.error (bool): Indicate whether the component is being displayed in an error state, inherited from FormControl error prop
  • value.filled (bool): Indicate whether input is filled
  • value.focused (bool): Indicate whether the component and its children are being displayed in a focused state
  • value.fullWidth (bool): Indicate whether the component is taking up the full width of its container, inherited from FormControl fullWidth prop
  • value.hiddenLabel (bool): Indicate whether the label is being hidden, inherited from FormControl hiddenLabel prop
  • value.required (bool): Indicate whether the label is indicating that the input is required input, inherited from the FormControl required prop
  • value.size (string): The size of the component, inherited from the FormControl size prop
  • value.variant (string): The variant is being used by the FormControl component and its children, inherited from FormControl variant prop
  • value.onBlur (func): Should be called when the input is blurred
  • value.onFocus (func): Should be called when the input is focused
  • value.onEmpty (func): Should be called when the input is emptied
  • value.onFilled (func): Should be called when the input is filled

Performance

Global styles for the auto-fill keyframes are injected and removed on each mount and unmount, respectively. If you are loading a large number of Text Field components at once, it might be a good idea to change this default behavior by enabling disableInjectingGlobalStyles in MuiInputBase. Make sure to inject GlobalStyles for the auto-fill keyframes at the top of your application.

import { GlobalStyles, createTheme, ThemeProvider } from '@mui/material';

const theme = createTheme({
  components: {
    MuiInputBase: {
      defaultProps: {
        disableInjectingGlobalStyles: true,
      },
    },
  },
});

export default function App() {
  return (
    <ThemeProvider theme={theme}>
      <GlobalStyles
        styles={{
          '@keyframes mui-auto-fill': { from: { display: 'block' } },
          '@keyframes mui-auto-fill-cancel': { from: { display: 'block' } },
        }}
      />
      ...
    </ThemeProvider>
  );
}

Limitations

Shrink

The input label "shrink" state isn't always correct. The input label is supposed to shrink as soon as the input is displaying something. In some circumstances, we can't determine the "shrink" state (number input, datetime input, Stripe input). You might notice an overlap.

shrink

To workaround the issue, you can force the "shrink" state of the label.

<TextField InputLabelProps={{ shrink: true }} />

or

<InputLabel shrink>Count</InputLabel>

Floating label

The floating label is absolutely positioned. It won't impact the layout of the page. Make sure that the input is larger than the label to display correctly.

type="number"

If you need a text field with number validation, you can use Base UI's Number Input instead.

You can follow this GitHub issue to track the progress of introducing the Number Input component to Material UI.

Helper text

The helper text prop affects the height of the text field. If two text fields are placed side by side, one with a helper text and one without, they will have different heights. For example:

Please enter your name

Press Enter to start editing

This can be fixed by passing a space character to the helperText prop:

Please enter your name

Press Enter to start editing

Integration with 3rd party input libraries

You can use third-party libraries to format an input. You have to provide a custom implementation of the <input> element with the inputComponent property.

The following demo uses the react-imask and react-number-format libraries. The same concept could be applied to e.g. react-stripe-element.

The provided input component should expose a ref with a value that implements the following interface:

interface InputElement {
  focus(): void;
  value?: string;
}
const MyInputComponent = React.forwardRef((props, ref) => {
  const { component: Component, ...other } = props;

  // implement `InputElement` interface
  React.useImperativeHandle(ref, () => ({
    focus: () => {
      // logic to focus the rendered component from 3rd party belongs here
    },
    // hiding the value e.g. react-stripe-elements
  }));

  // `Component` will be your `SomeThirdPartyComponent` from below
  return <Component {...other} />;
});

// usage
<TextField
  InputProps={{
    inputComponent: MyInputComponent,
    inputProps: {
      component: SomeThirdPartyComponent,
    },
  }}
/>;

Accessibility

In order for the text field to be accessible, the input should be linked to the label and the helper text. The underlying DOM nodes should have this structure:

<div class="form-control">
  <label for="my-input">Email address</label>
  <input id="my-input" aria-describedby="my-helper-text" />
  <span id="my-helper-text">We'll never share your email.</span>
</div>
  • If you are using the TextField component, you just have to provide a unique id unless you're using the TextField only client side. Until the UI is hydrated TextField without an explicit id will not have associated labels.
  • If you are composing the component:
<FormControl>
  <InputLabel htmlFor="my-input">Email address</InputLabel>
  <Input id="my-input" aria-describedby="my-helper-text" />
  <FormHelperText id="my-helper-text">We'll never share your email.</FormHelperText>
</FormControl>

Complementary projects

For more advanced use cases, you might be able to take advantage of:

Unstyled

Use the Base UI Text Field for complete ownership of the component's design, with no Material UI or Joy UI styles to override. This unstyled version of the component is the ideal choice for heavy customization with a smaller bundle size.
