Custom layout in SimpleForm component on react-admin

Question

I want to create a custom two-column-grid layout on my react-admin project on Edit and Show pages. I want to display selectboxes and the imageupload area on the left column, and the text inputs on the right column by using only one <SimpleForm>.

Simply like this

If I use a div or a <Card> component under <SimpleForm> and <EditController> components, I receive an error.

Warning: React does not recognize the `basePath` prop on a DOM element. 
If you intentionally want it to appear in the DOM as a custom 
attribute, spell it as lowercase `basepath` instead. If you 
accidentally passed it from a parent component, remove it from the DOM 
element.

Is there any way to create a layout without this error?

Answer 1

Actually, this could be done a little bit easier in case you don't need any custom styles and what not. In order to get rid of the basePath error, just sanitize the props passed to the Material UI Grid Component:

const SanitizedGrid = ({basePath, ...props}) => {
  return (
    <Grid {...props} />
  );
};

Then use it in place of a normal Grid:

export default props => (
  <SimpleForm {...props}>
    <SanitizedGrid container spacing={16}>
        <Grid item xs>
            <TextInput source="name" />
        </Grid>
    </SanitizedGrid>
  </SimpleForm>
);

I solved it with creating another component with using divs, <Grid/> etc, and used that component in <SimpleForm> component.

import {withStyles} from '@material-ui/core/styles';
import React from 'react';
import {
    EditController,
    SimpleForm,
    TextInput,
    SelectInput,
    Title,
} from 'react-admin';
import Grid from '@material-ui/core/Grid';
import Card from '@material-ui/core/Card';
import Poster from "../customField/Poster";
import {EditToolbar} from '../toolbar/CustomToolbar'
import {EditActions} from '../toolbar/CustomActions'

const editStyles = {
    root: {display: 'flex', alignItems: 'flex-start', width: '100%'},
    form: {flexGrow: 9},
};


class CardEdit extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            refresh: false
        };
    }

    render() {
        const FormDiv = withStyles(editStyles)(({children, classes, ...props}) => {
                return (
                    <div className={classes.root}>
                        <div className={classes.form}>
                            <Grid container spacing={24}>
                                <Grid item xs={6}>
                                    <TextInput source="name" fullWidth />
                                </Grid>
                                <Grid item xs={6}>
                                    <TextInput source="card_id" fullWidth />
                                </Grid>
                            </Grid>
                        </div>
                        </div>
                )
            }
        )

        return (
        <EditController {...this.props}>
            {({resource, record, redirect, save, basePath, version}) => {
                return (
                <div>
                    <Title defaultTitle="sample"/>
                    <Card>
                        <div style={{ margin: '20px 20px 0 0' }}>
                            <EditActions
                                basePath={basePath}
                                resource={resource}
                                data={record}
                                hasShow
                                hasList
                            />
                        </div>
                        {record && (
                            <SimpleForm
                                basePath={basePath}
                                redirect={redirect}
                                resource={resource}
                                record={record}
                                save={save}
                                version={version}
                                toolbar={<EditToolbar/>}
                            >

                                <FormDiv record={record} />
                            </SimpleForm>
                        )}
                    </Card>
                </div>
            )
            }}
        </EditController>
        )
    }
}

export default withStyles(editStyles)(CardEdit);
