Radio Group

The Radio Group allows the user to select one option from a set.

Use radio buttons when the user needs to see all available options. If available options can be collapsed, consider using a Select component because it uses less space.

Radio buttons should have the most commonly used option selected by default.

Choose wisely


Here is an example of customizing the component. You can learn more about this in the overrides documentation page.


For advanced customization use cases, a useRadioGroup() hook is exposed. It returns the context value of the parent radio group. The Radio component uses this hook internally.


import { useRadioGroup } from '@mui/material/RadioGroup';


value (object):

  • (string [optional]): The name used to reference the value of the control.
  • value.onChange (func [optional]): Callback fired when a radio button is selected.
  • value.value (any [optional]): Value of the selected radio button.

When to use



  • All form controls should have labels, and this includes radio buttons, checkboxes, and switches. In most cases, this is done by using the <label> element (FormControlLabel).

  • When a label can't be used, it's necessary to add an attribute directly to the input component. In this case, you can apply the additional attribute (for example aria-label, aria-labelledby, title) via the inputProps property.

    'aria-label': 'Radio A',
