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          


        

Answer 1

To have multiple classes applied to a component, wrap the classes you would like to apply within classNames.

For example, in your situation, your code should look like this,

import classNames from 'classnames';

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

Make sure that you import classNames!!!

Have a look at material ui documentation where they use multiple classes in one component to create a customized button
