Full width material-ui Button within a Badge?

Question

I have a Button inside a Grid and was using fullWidth to expand it to fill the container.

This worked fine, until I wrapped it in a Badge. Now the fullWidth property is ignored and the button is default width.

Worked fine:

<Button variant={"outlined"} color={"secondary"} fullWidth>
    Todo
</Button>

Now not working:

<Badge badgeContent={4} color={"secondary"}>
    <Button variant={"outlined"} color={"secondary"} fullWidth>
        Todo
    </Button>
</Badge>

How can I get the button to expand to fill its parent?

import React, {Component} from 'react';
import Grid from "@material-ui/core/Grid/Grid";
import Button from "@material-ui/core/Button/Button";
import Badge from "@material-ui/core/Badge/Badge";


export default class App extends Component {
    render() {
        return (

            <Grid container style={{margin: 10}}>
                <Grid item xs={2}>

                    <Badge badgeContent={4} color={"secondary"}>
                        <Button variant={"outlined"} color={"secondary"} fullWidth>
                            Todo badge
                        </Button>
                    </Badge>

                    <Button variant={"outlined"} color={"secondary"} fullWidth>
                        Todo no badge
                    </Button>
                </Grid>
                <Grid item xs={10}>

                </Grid>
            </Grid>
        );
    }
};

Solution 1

you have to apply fullWidth property to badge

<Badge badgeContent={4} color={"secondary"} fullWidth>
    <Button variant={"outlined"} color={"secondary"}>
        Todo
    </Button>
</Badge>

Solution 2

I could come up with a solution using width CSS property:

here is my answer:

const styles = theme => ({
  margin: {
    margin: theme.spacing.unit * 2,
    width: '100%'
  }
});

function SimpleBadge(props) {
  const { classes } = props;
  return (
    <Grid container>
      <Grid item xs={11}>
      <Badge color="primary" badgeContent={4} className={classes.margin} >
        <Button variant="contained" fullWidth>Button</Button>
      </Badge>

      </Grid>
    </Grid>
  );
}

please find that I have used width: '100%' in badge styles.

hope this will help you.

This didn't work for me. (Sorry, should have mentioned I tried this)

Did you try adding it to badge?

[Duncan Jones]

Yes, exactly as you suggest.

[samnu pel]

check in dev tools is badge width is fullWidth or not? If it is fullWidth and button width is not fullWidth then apply fullWidth property for both.

[Duncan Jones]

Even if I apply it to both elements, it doesn't work. Are you guessing here, or is this working for you locally?

[samnu pel]

its working for me. may be some parent classes doing this.

I’ve included a failing example in my question.
