<Edit> provides us a layout for displaying the page. It does not contain any logic but adds extra functionalities like a <RefreshButton>.
We will show what <Edit> does using properties with examples.
import React from "react";

        formState: { errors },
    } = useForm();
    const samplesData = queryResult?.data?.data;

                    )}
                />
            </Box>
        </Edit>
    );
};
You can swizzle this component to customize it with the refine CLI
Properties
title
It allows adding title inside the <Edit> component. if you don't pass title props it uses "Edit" prefix and singular resource name by default. For example, for the /posts/edit resource, it will be "Edit post".
import { Edit } from "@refinedev/mui";
import { Typography } from "@mui/material";
const EditPage: React.FC = () => {
    return (
        <Edit
            title={<Typography variant="h5">Custom Title</Typography>}
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
resource
The <Edit> component reads the resource information from the route by default. If you want to use a custom resource for the <Edit> component, you can use the resource prop.
import { Edit } from "@refinedev/mui";
const CustomPage: React.FC = () => {
    return (
        <Edit resource="posts" recordItemId={123}>
            <span>Rest of your page here</span>
        </Edit>
    );
};
The <Edit> component has a save button by default. If you want to customize this button you can use the saveButtonProps property like the code below.
Clicking on the save button will submit your form.
Refer to the <SaveButton> documentation for detailed usage. →
import { Edit } from "@refinedev/mui";
const PostEdit: React.FC = () => {
    return (
        <Edit saveButtonProps={{ size: "small" }}>
            <span>Rest of your page here</span>
        </Edit>
    );
};
canDelete allows us to add the delete button inside the <Edit> component. If the resource has the canDelete property, refine adds the delete button by default. If you want to customize this button you can use the deleteButtonProps property like the code below.
When clicked on, the delete button executes the useDelete method provided by the dataProvider.
Refer to the <DeleteButton> documentation for detailed usage. →
import { Edit } from "@refinedev/mui";
import { usePermissions } from "@refinedev/core";
const PostEdit: React.FC = () => {
    const { data: permissionsData } = usePermissions();
    return (
        <Edit
            canDelete={permissionsData?.includes("admin")}
            deleteButtonProps={{ size: "small" }}
            saveButtonProps={{ size: "small" }}
        >
            <p>Rest of your page here</p>
        </Edit>
    );
};
Refer to the usePermission documentation for detailed usage. →
recordItemId
The <Edit> component reads the id information from the route by default. recordItemId is used when it cannot read from the URL(when used on a custom page, modal or drawer).
import { Edit } from "@refinedev/mui";
const CustomPage: React.FC = () => {
    return (
        <Edit resource="posts" recordItemId={123}>
            <span>Rest of your page here</span>
        </Edit>
    );
};
The <Edit> component needs the id information for the <RefreshButton> to work properly.
mutationMode
Determines which mode mutation will have while executing <DeleteButton>.
Refer to the mutation mode docs for further information. →
import React from "react";
import { Edit, useAutocomplete } from "@refinedev/mui";
import { TextField, Autocomplete, Box } from "@mui/material";
import { useForm } from "@refinedev/react-hook-form";
import { Controller } from "react-hook-form";
const SampleEdit = () => {
    const {
        saveButtonProps,
        refineCore: { queryResult },
        register,
        control,
        formState: { errors },
    } = useForm();
    const samplesData = queryResult?.data?.data;
    const { autocompleteProps: categoryAutocompleteProps } = useAutocomplete({
        resource: "categories",
        defaultValue: samplesData?.category?.id,
    });
    return (
        <Edit
            saveButtonProps={saveButtonProps}

                autoComplete="off"
            >
                <TextField

                            isOptionEqualToValue={(option, value) =>
                                value === undefined || option?.id?.toString() === (value?.id ?? value)?.toString()

                />
            </Box>
        </Edit>
    );
};
dataProviderName
If not specified, Refine will use the default data provider. If you have multiple data providers and want to use a different one, you can use the dataProviderName property.
import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";
import { Edit } from "@refinedev/mui";
const PostEdit = () => {
    return <Edit dataProviderName="other">...</Edit>;
};
export const App: React.FC = () => {
    return (
        <Refine
            dataProvider={{
                default: dataProvider("https://api.fake-rest.refine.dev/"),
                other: dataProvider("https://other-api.fake-rest.refine.dev/"),
            }}
        >
            {}
        </Refine>
    );
};
goBack
To customize the back button or to disable it, you can use the goBack property.
import { Edit } from "@refinedev/mui";
import { Button } from "@mui/material";
import { useBack } from "@refinedev/core";
const BackButton = () => {
    const goBack = useBack();
    return <Button onClick={() => goBack()}>BACK!</Button>;
};
const PostEdit: React.FC = () => {
    return (
        <Edit
            goBack={<BackButton />}
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
isLoading
To toggle the loading state of the <Edit/> component, you can use the isLoading property.
import { Edit } from "@refinedev/mui";
const PostEdit: React.FC = () => {
    const [loading, setLoading] = React.useState(true);
    return (
        <Edit
            isLoading={loading}
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
breadcrumb
To customize or disable the breadcrumb, you can use the breadcrumb property. By default it uses the Breadcrumb component from @refinedev/mui package.
Refer to the Breadcrumb documentation for detailed usage. →
This feature can be managed globally via the <Refine> component's options
import { Edit, Breadcrumb } from "@refinedev/mui";
const PostEdit: React.FC = () => {
    return (
        <Edit
            breadcrumb={
                <div
                    style={{
                        padding: "3px 6px",
                        border: "2px dashed cornflowerblue",
                    }}
                >
                    <Breadcrumb />
                </div>
            }
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
wrapperProps
If you want to customize the wrapper of the <Edit/> component, you can use the wrapperProps property.
Refer to the Card documentation from Material UI for detailed usage. →
import { Edit } from "@refinedev/mui";
const PostEdit: React.FC = () => {
    const [loading, setLoading] = React.useState(true);
    return (
        <Edit
            wrapperProps={{
                sx: {
                    backgroundColor: "lightsteelblue",
                },
            }}
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
If you want to customize the header of the <Edit/> component, you can use the headerProps property.
Refer to the CardHeader documentation from Material UI for detailed usage. →
import { Edit } from "@refinedev/mui";
const PostEdit: React.FC = () => {
    const [loading, setLoading] = React.useState(true);
    return (
        <Edit
            headerProps={{
                sx: {
                    backgroundColor: "lightsteelblue",
                },
            }}
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
contentProps
If you want to customize the content of the <Edit/> component, you can use the contentProps property.
Refer to the CardContent documentation from Material UI for detailed usage. →
import { Edit } from "@refinedev/mui";
const PostEdit: React.FC = () => {
    const [loading, setLoading] = React.useState(true);
    return (
        <Edit
            contentProps={{
                sx: {
                    backgroundColor: "lightsteelblue",
                },
            }}
        >
            <span>Rest of your page here</span>
        </Edit>
    );
};
You can customize the buttons at the header by using the headerButtons property. It accepts React.ReactNode or a render function ({ defaultButtons }) => React.ReactNode which you can use to keep the existing buttons and add your own.
import { Edit } from "@refinedev/mui";
import { Button } from "@mui/material";
const PostEdit: React.FC = () => {
    const [loading, setLoading] = React.useState(true);
    return (
        <Edit
