Material-ui: underlineStyle not working on TextField

[mishotek]

I want to remove underline from the TextField
This is my code:

import React from "react";
import TextField from "@material-ui/core/es/TextField/TextField";

class SearchBox extends React.Component {

    render() {
        return (
            <div>
                <TextField
                    placeholder={"Search"}
                    underlineStyle={{display: 'none'}}
                />
            </div>
        )
    }
}

export default SearchBox;

This code doesn't remove the underline and I'm getting this error message in console:

Warning: React does not recognize the `underlineStyle` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `underlinestyle` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

How can I remove the underline?

Textfield doesn't have an underlineStyle prop. You'll need to use classes.
