How to style helperText in the TextField material-ui component

Add custom styles to the “material-ui” component may be a challenge sometimes.

For example, I need to add additional custom styles to the “TextField” component.

I tried different solutions and spent a lot of time to find the most simple one.

In the end, I found that it is a possible just pass “FormHelperTextProps” property with “className” key.

	<TextField
	FormHelperTextProps={{
	className: classes.helperText
	}}
	/>
