I'm new at React JS. currently I'm using Material-UI for building small reusable components. Is there any way to make Material-UI radio buttons required?
like an input field showing "This field is required" text when empty
You can use name property and add the required property to radio component (change the values to your value property):
<RadioGroup name="nameRadio" value={''}>
<FormControlLabel
value={'value1'}
control={<Radio required={true} />}
label={'Label 1'}
/>
<FormControlLabel
value={'value2'}
control={<Radio required={true} />}
label={'Label 2'}
/>
</RadioGroup>
