A helpful tip on how to designate a specific color to the helperText in Material UI in order to emphasize

Is there a way to customize the color of helperText in material-UI for highlighting errors in a TextField? I've been struggling to change the color of helperText with no success.

I attempted using MuiFormHelperText-root-406 to add CSS styles, but it didn't yield the desired results.

<Grid item xs={3}>
   <TextField
       label="EmailId" 
       name="emailId" 
       value={editItem.emailId} 
       onChange={this.editInputValue} 
       helperText={this.state.emailerror}  />      
</Grid>


.MuiFormHelperText-root-406{
   color:rgba(255,0,0,0.5);
 }

Answer №1

Make sure to include the following code snippet: add className={classes.textField} within the TextField component

  textField: {
    marginLeft: theme.spacing(1),
    marginRight: theme.spacing(1),
    width: 200,
    '& p':{
      color:'blue',
    },
  },

      <TextField
        id="standard-helperText"
        label="Helper text"
        defaultValue="Default Value"
        className={classes.textField}
        helperText="Some important text"
        margin="normal"
      />

@arpita-patel's response is accurate, but it's worth noting that you also have the option to include this in your CSS:

.CustomFormHelperText {
    color:rgba(255,0,0,0.5);
}

Alternatively, you can specify it based on the parent element:

.CustomTextField p {
    color:rgba(255,0,0,0.5);
}

Both methods worked successfully for me with Material UI version 4.0.2

Answer №3

In my experience, I have found a great way to customize the appearance of the helperText for the TextField component, which is similar to the method outlined by Arpita Patel. The only tweak I have made is using the attribute classes instead of className, as detailed in the Material-UI documentation.

According to the documentation, the TextField component can only utilize one CSS rule name, which is root (the global class is .MuiTextField-root).

Therefore, to style the helperText to your liking, you can use the following code:

JSX (based on your initial code example)

const classes = useStyles();

<TextField
  label="EmailId" 
  name="emailId" 
  value={editItem.emailId} 
  onChange={this.editInputValue} 
  helperText={this.state.emailerror}
  classes={{root: classes.textField}}
/>

STYLE via makeStyles

import { makeStyles } from '@material-ui/core/styles';

const useStyles = makeStyles((theme) => ({
  textField: {
    '& p':{
      /* your style for helperText here*/
    }
  }
})

Performing this task has become simpler:

Just include the sx prop in the TextField component

sx={ "& p": { //custom styles for your helper text } }

Answer №5

I personally prefer leveraging the sx prop over other solutions. In this specific case, I find it beneficial to utilize it within the FormHelperTextProps like so:

<TextField
       label="EmailId" 
       name="emailId" 
       value={editItem.emailId} 
       onChange={this.editInputValue} 
       helperText={this.state.emailerror}
       FormHelperTextProps={{
              sx: {
                color: "red",
              }
            }}
      />
