Add <InPlaceEditor> for edit-in-place

[fzaninotto]

Problem

To edit a value from a record, users have to leave the current screen to go to an Edit view (or use EditInDialog, but they will also lose context).

Solution

<InPlaceEditor> renders a field from the current record. On click, it switches to an editable state, allowing the user to change the value directly.

InPlaceEditor.mp4

Use this component to let users edit parts of a record directly in the list or detail view. It is useful for quick edits without navigating to a separate edit page.

import { Show, InPlaceEditor } from 'react-admin';
import { Stack, Box, Typography } from '@mui/material';

const CustomerShow = () => (
    <Show>
        <Stack direction="row" spacing={2}>
            <AvatarField />
            <CustomerActions />
            <Box sx={{ display: 'flex', justifyContent: 'center' }}>
                <Typography>Phone</Typography>
                <InPlaceEditor source="phone" />
            </Box>
            <Box sx={{ display: 'flex', justifyContent: 'center' }}>
                <Typography>Email</Typography>
                <InPlaceEditor source="email" />
            </Box>
            ...
        </Stack>
    </Show>
);

The field changes color on hover, to indicate that it is editable. The user can cancel the edit by pressing Escape. The field is saved automatically when the user clicks outside of it or presses Enter. While it is being saved, the field is disabled and a loading spinner is shown. If the save fails, an error message is displayed and the original value is restored.

This component can even help replace the <EditableDatagrid>:

Other than that this new component works very well and the UX is 👌
