Make Material-UI Reactjs FloatingActionButton float

Question

After trying to find an example where the FloatingActionButton floats at its standard bottom-right screen position with no results, I come to you if you could provide one because it seems to be a normal button without floating to that corner by default.

Am I supposed to make it float by setting custom CSS rules? Material-UI docs doesn't mention any property about floating Material-UI FloatingActionButton documentation.

Answer 1

Indeed, no property for this in the component FloatingActionButton for the moment.

Waiting for it :

1) A solution using inline styles :

At the top of your component, add :

const style = {
    margin: 0,
    top: 'auto',
    right: 20,
    bottom: 20,
    left: 'auto',
    position: 'fixed',
};

... and in your render method :

render() {
    return <FloatingActionButton style={style}><ContentAdd /></FloatingActionButton>
}

OR

2) A solution using CSS file

Add in your CSS file (ex : styles.css referenced on your index.html) :

.fab {
    margin: 0px;
    top: auto;
    right: 20px;
    bottom: 20px;
    left: auto;
    position: fixed;
};

... and put on your React component :

render() {
    return <FloatingActionButton className="fab"><ContentAdd /></FloatingActionButton>
}

I actually found this on the Material-UI documentation. I just made a few tweaks to it. Here's the resulting code.

import { makeStyles } from '@material-ui/core/styles';
import Fab from '@material-ui/core/Fab';
import AddIcon from '@material-ui/icons/Add';

const useStyles = makeStyles(theme => ({
  fab: {
    position: 'fixed',
    bottom: theme.spacing(2),
    right: theme.spacing(2),
  },
}));

add this to your component

const classes = useStyles();

return (
  <Fab color="primary" aria-label="add" className={classes.fab}>
    <AddIcon />
  </Fab>
);

If you want to manipulate CSS in material-ui, its better to use withStyles currying function.

Like this:

import React, {Component} from 'react';
import {Button} from "material-ui";
import {Add} from 'material-ui-icons';
import { withStyles } from 'material-ui/styles';
const style = theme => ({
  fab: {
    margin: 0,
    top: 'auto',
    left: 20,
    bottom: 20,
    right: 'auto',
    position: 'fixed',

  }
});
class MyPage extends Component{
render() {
    const {classes} = this.props;
        return <Button fab variant="fab" color="primary" aria-label="add" className={classes.fab}><Add />
    </Button>
}
export default withStyles(style)(MyPage);
