Question: Is it possible to uglify all the RequireJS modules without concatenating them into a single file? (I know the other way round is possible with `optimize: "none"`).

Answer: 
Material UI have implemented their own Flexbox layout via the [Grid component](https://material-ui.com/components/grid/). 

It appears they [initially wanted](https://github.com/callemall/material-ui/issues/3614#issuecomment-193119929) to keep themselves as purely a 'components' library. But one of the core developers [decided it was too important not to have their own](https://github.com/callemall/material-ui/issues/3614#issuecomment-250996378). It has now been [merged into the core code](https://github.com/callemall/material-ui/pull/5808) and was [released with v1.0.0](https://github.com/mui-org/material-ui/releases/tag/v1.0.0).

You can install it via:

```
npm install @material-ui/core

```

It is now in the official [documentation with code examples](https://material-ui.com/components/grid/).
I looked around for an answer to this and the best way I found was to use Flex and inline styling on different components.

For example, to make two paper components divide my full screen in 2 vertical components (in ration of 1:4), the following code works fine. 

```
const styles = {
  div:{
    display: 'flex',
    flexDirection: 'row wrap',
    padding: 20,
    width: '100%'
  },
  paperLeft:{
    flex: 1,
    height: '100%',
    margin: 10,
    textAlign: 'center',
    padding: 10
  },
  paperRight:{
    height: 600,
    flex: 4,
    margin: 10,
    textAlign: 'center',
  }
};

class ExampleComponent extends React.Component {
  render() {
    return (
      <div>
        <div style={styles.div}>
          <Paper zDepth={3} style={styles.paperLeft}>
            <h4>First Vertical component</h4>
          </Paper>
          <Paper zDepth={3} style={styles.paperRight}>
              <h4>Second Vertical component</h4>
          </Paper>
        </div>
      </div>
    )
  }
}

```

Now, with some more calculations, you can easily divide your components on a page.
