Show

<Show> provides us a layout for displaying the page. It does not contain any logic and just adds extra functionalities like a refresh button or giving title to the page.

We will show what <Show> does using properties with examples.

localhost:3000/posts/show/123
import React from "react";
import { useShow, useOne } from "@refinedev/core";
import {
  Show,
  NumberField,
  TextFieldComponent as TextField,
  MarkdownField,
  DateField,
} from "@refinedev/mui";
import { Stack, Typography } from "@mui/material";

const SampleShow = () => {
  const { queryResult } = useShow();
  const { data, isLoading } = queryResult;

  const record = data?.data;

  const { data: categoryData, isLoading: categoryIsLoading } = useOne({
    resource: "categories",
    id: record?.category?.id || "",
    queryOptions: {
      enabled: !!record,
    },
  });

  return (
    <Show isLoading={isLoading}>
      <Stack gap={1}>
        <Typography variant="body1" fontWeight="bold">
          Id
        </Typography>
        <NumberField value={record?.id ?? ""} />
        <Typography variant="body1" fontWeight="bold">
          Title
        </Typography>
        <TextField value={record?.title} />
        <Typography variant="body1" fontWeight="bold">
          Content
        </Typography>
        <MarkdownField value={record?.content} />
        <Typography variant="body1" fontWeight="bold">
          Category
        </Typography>
        {categoryIsLoading ? <>Loading...</> : <>{categoryData?.data?.title}</>}
        <Typography variant="body1" fontWeight="bold">
          Created At
        </Typography>
        <DateField value={record?.createdAt} />
      </Stack>
    </Show>
  );
};
Good to know:

You can swizzle this component with the Refine CLI to customize it.

Properties​

title​

title allows the addition of titles inside the <Show> component. if you don't pass title props it uses the "Show" prefix and the singular resource name by default. For example, for the "posts" resource, it would be "Show post".

localhost:3000/posts/create
import { Show } from "@refinedev/mui";
import { Typography } from "@mui/material";

const ShowPage: React.FC = () => {
  return (
    <Show
      title={<Typography variant="h5">Custom Title</Typography>}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

resource​

The <Show> component reads the resource information from the route by default. If you want to use a custom resource for the <Show> component, you can use the resource prop.

localhost:3000/custom
import { Show } from "@refinedev/mui";

const CustomPage: React.FC = () => {
  return (
    <Show resource="posts" recordItemId={123}>
      <span>Rest of your page here</span>
    </Show>
  );
};

If you have multiple resources with the same name, you can pass the identifier instead of the name of the resource. It will only be used as the main matching key for the resource, data provider methods will still work with the name of the resource defined in the <Refine/> component.

For more information, refer to the identifier of the <Refine/> component documentation →

canDelete and canEdit​

canDelete and canEdit allows us to add the delete and edit buttons inside the <Show> component. If the resource has canDelete or canEdit property Refine adds the buttons by default.

When clicked on, delete button executes the useDelete method provided by the dataProvider and the edit button redirects the user to the record edit page.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";
import { usePermissions } from "@refinedev/core";

const PostShow: React.FC = () => {
  const { data: permissionsData } = usePermissions();
  return (
    <Show
      canDelete={permissionsData?.includes("admin")}
      canEdit={
        permissionsData?.includes("editor") ||
        permissionsData?.includes("admin")
      }
    >
      <p>Rest of your page here</p>
    </Show>
  );
};

For more information, refer to the <DeleteButton> →, <EditButton> → and usePermission → documentations.

recordItemId​

<Show> 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).

localhost:3000/custom
import { Show } from "@refinedev/mui";

const CustomPage: React.FC = () => {
  return (
    <Show resource="posts" recordItemId={123}>
      <span>Rest of your page here</span>
    </Show>
  );
};

<Show> component needs the id information for <RefreshButton> to work properly.

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 { Show } from "@refinedev/mui";

const PostShow = () => {
  return <Show dataProviderName="other">...</Show>;
};

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.

localhost:3000/posts/show/123
import { Show } 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 PostShow: React.FC = () => {
  return (
    <Show
      goBack={<BackButton />}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

isLoading​

To toggle the loading state of the <Show/> component, you can use the isLoading property.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      isLoading={loading}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

breadcrumb
Globally Configurable
This value can be configured globally. Click to see the guide for more information.
​

To customize or disable the breadcrumb, you can use the breadcrumb property. By default it uses the Breadcrumb component from @refinedev/mui package.

localhost:3000/posts/show/123
import { Show, Breadcrumb } from "@refinedev/mui";

const PostShow: React.FC = () => {
  return (
    <Show
      breadcrumb={
        <div
          style={{
            padding: "3px 6px",
            border: "2px dashed cornflowerblue",
          }}
        >
          <Breadcrumb />
        </div>
      }
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

For more information, refer to the Breadcrumb documentation →

wrapperProps​

If you want to customize the wrapper of the <Show/> component, you can use the wrapperProps property.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      wrapperProps={{
        sx: {
          backgroundColor: "lightsteelblue",
        },
      }}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

For more information, refer to the Card documentation from Material UI →

headerProps​

If you want to customize the header of the <Show/> component, you can use the headerProps property.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      headerProps={{
        sx: {
          backgroundColor: "lightsteelblue",
        },
      }}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

For more information, refer to the CardHeader documentation from Material UI →

contentProps​

If you want to customize the content of the <Show/> component, you can use the contentProps property.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      contentProps={{
        sx: {
          backgroundColor: "lightsteelblue",
        },
      }}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

For more information, refer to the CardContent documentation from Material UI →

headerButtons​

By default, the <Show/> component has a <ListButton>, <EditButton>, <DeleteButton>, and, <RefreshButton> at the header.

You can customize the buttons at the header by using the headerButtons property. It accepts React.ReactNode or a render function ({ defaultButtons, deleteButtonProps, editButtonProps, listButtonProps, refreshButtonProps }) => React.ReactNode which you can use to keep the existing buttons and add your own.

If "list" resource is not defined, the <ListButton> will not render and listButtonProps will be undefined.

If canDelete is false, the <DeleteButton> will not render and deleteButtonProps will be undefined.

If canEdit is false, <EditButton> will not render and editButtonProps will be undefined.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      headerButtons={({ defaultButtons }) => (
        <>
          {defaultButtons}
          <Button type="primary">Custom Button</Button>
        </>
      )}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

Or, instead of using the defaultButtons, you can create your own buttons. If you want, you can use createButtonProps to utilize the default values of the <ListButton>, <EditButton>, <DeleteButton>, and, <RefreshButton> components.

localhost:3000/posts/show/123
import {
  Show,
  ListButton,
  EditButton,
  DeleteButton,
  RefreshButton,
} from "@refinedev/mui";
import { Button } from "@mui/material";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      headerButtons={({
        deleteButtonProps,
        editButtonProps,
        listButtonProps,
        refreshButtonProps,
      }) => (
        <>
          <Button type="primary">Custom Button</Button>
          {listButtonProps && (
            <ListButton {...listButtonProps} meta={{ foo: "bar" }} />
          )}
          {editButtonProps && (
            <EditButton {...editButtonProps} meta={{ foo: "bar" }} />
          )}
          {deleteButtonProps && (
            <DeleteButton {...deleteButtonProps} meta={{ foo: "bar" }} />
          )}
          <RefreshButton {...refreshButtonProps} meta={{ foo: "bar" }} />
        </>
      )}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

headerButtonProps​

You can customize the wrapper element of the buttons at the header by using the headerButtonProps property.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      headerButtonProps={{
        sx: {
          backgroundColor: "lightsteelblue",
        },
      }}
      headerButtons={({ defaultButtons }) => (
        <>
          {defaultButtons}
          <Button type="primary">Custom Button</Button>
        </>
      )}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

footerButtons​

You can customize the buttons at the footer by using the footerButtons 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.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      footerButtons={({ defaultButtons }) => (
        <>
          {defaultButtons}
          <Button type="primary">Custom Button</Button>
        </>
      )}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};

footerButtonProps​

You can customize the wrapper element of the buttons at the footer by using the footerButtonProps property.

localhost:3000/posts/show/123
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";

const PostShow: React.FC = () => {
  const [loading, setLoading] = React.useState(true);

  return (
    <Show
      footerButtonProps={{
        sx: {
          backgroundColor: "lightsteelblue",
        },
      }}
      footerButtons={({ defaultButtons }) => (
        <>
          {defaultButtons}
          <Button type="primary">Custom Button</Button>
        </>
      )}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};
