css - How to add multiple classes in Material UI using the classes props?

Question

Using the css-in-js method to add classes to a react component, how do I add multiple components?

Here is the classes variable:

const styles = theme => ({
  container: {
    display: 'flex',
    flexWrap: 'wrap'
  },
  spacious: {
    padding: 10
  },
});

Here is how I used it:

return (<div className={ this.props.classes.container }>)

The above works, but is there a way to add both classes, without using the classNames npm package? Something like:

<div className={ this.props.classes.container + this.props.classes.spacious}>

Answer 1

you can use string interpolation:

<div className={`${this.props.classes.container} ${this.props.classes.spacious}`}>
