<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.

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
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 ShowPage = () => {
  const {
    result: product,
    query: { isLoading },
  } = useShow();

  const {
    result: category,
    query: { isLoading: categoryIsLoading },
  } = useOne({
    resource: "categories",
    id: product?.category?.id || "",
    queryOptions: {
      enabled: !!product,
    },
  });

  return (
    <Show isLoading={isLoading}>
      <Stack gap={1}>
        <Typography variant="body1" fontWeight="bold">
          Id
        </Typography>
        <NumberField value={product?.id ?? ""} />
        <Typography variant="body1" fontWeight="bold">
          Title
        </Typography>
        <TextField value={product?.title} />
        <Typography variant="body1" fontWeight="bold">
          Content
        </Typography>
        <MarkdownField value={product?.content} />
        <Typography variant="body1" fontWeight="bold">
          Category
        </Typography>
        {categoryIsLoading ? <>Loading...</> : <>{category?.title}</>}
        <Typography variant="body1" fontWeight="bold">
          Created At
        </Typography>
        <DateField value={product?.createdAt} />
      </Stack>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: "/posts",

          path="/posts"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>
          }
        >
          <ReactRouter.Route index element={<SampleList />} />
        </ReactRouter.Route>
        <ReactRouter.Route
          path="/posts/show/:id"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>

  </ReactRouter.BrowserRouter>,
);

:::simple 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".

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
import { Show } from "@refinedev/mui";
import { Typography } from "@mui/material";

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

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: "/posts",
          show: "/posts/show/:id",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/posts/show/:id"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>
          }
        >
          <ReactRouter.Route index element={<ShowPage />} />
        </ReactRouter.Route>
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

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.

tsx
setInitialRoutes(["/custom"]);

// visible-block-start
import { Show } from "@refinedev/mui";

const CustomPage: React.FC = () => {
  return (
    /* highlight-next-line */
    <Show resource="posts" recordItemId={123}>
      <span>Rest of your page here</span>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: "/posts",
          show: "/posts/show/:id",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/custom"
          element={
            <div style={{ padding: 16 }}>
              <CustomPage />
            </div>
          }
        />
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

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 &#8594

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.

tsx
setInitialRoutes(["/posts/show/123"]);
const { default: simpleRest } = RefineSimpleRest;

const dataProvider = simpleRest("https://api.fake-rest.refine.dev");

const customDataProvider = {
  ...dataProvider,
  deleteOne: async ({ resource, id, variables }) => {
    return {
      data: {},
    };
  },
};

const authProvider = {
  login: async () => {
    return {
      success: true,
      redirectTo: "/",
    };
  },
  register: async () => {
    return {
      success: true,
    };
  },
  forgotPassword: async () => {
    return {
      success: true,
    };
  },
  updatePassword: async () => {
    return {
      success: true,
    };
  },
  logout: async () => {
    return {
      success: true,
      redirectTo: "/",
    };
  },
  check: async () => ({
    authenticated: true,
  }),
  onError: async (error) => {
    console.error(error);
    return { error };
  },
  getPermissions: async () => ["admin"],
  getIdentity: async () => null,
};

// visible-block-start
import { Show } from "@refinedev/mui";
import { usePermissions } from "@refinedev/core";

const ShowPage: React.FC = () => {
  const { data: permissionsData } = usePermissions();
  return (
    <Show
      /* highlight-start */
      canDelete={permissionsData?.includes("admin")}
      canEdit={
        permissionsData?.includes("editor") ||
        permissionsData?.includes("admin")
      }
      /* highlight-end */
    >
      <p>Rest of your page here</p>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      authProvider={authProvider}
      dataProvider={customDataProvider}
      resources={[
        {
          name: "posts",
          list: "/posts",
          show: "/posts/show/:id",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/posts/show/:id"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>
          }
        >
          <ReactRouter.Route index element={<PostShow />} />
        </ReactRouter.Route>
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

For more information, refer to the <DeleteButton> &#8594, <EditButton> &#8594 and usePermission &#8594 documentations.

deleteButtonProps

If the resource has the canDelete property and you want to customize this button, you can use the deleteButtonProps property like the code below.

tsx
setInitialRoutes(["/posts/show/123"]);

const { default: simpleRest } = RefineSimpleRest;

const dataProvider = simpleRest("https://api.fake-rest.refine.dev");

const customDataProvider = {
  ...dataProvider,
  deleteOne: async ({ resource, id, variables }) => {
    return {
      data: {},
    };
  },
};

const authProvider = {
  login: async () => {
    return {
      success: true,
      redirectTo: "/",
    };
  },
  register: async () => {
    return {
      success: true,
    };
  },
  forgotPassword: async () => {
    return {
      success: true,
    };
  },
  updatePassword: async () => {
    return {
      success: true,
    };
  },
  logout: async () => {
    return {
      success: true,
      redirectTo: "/",
    };
  },
  check: async () => ({
    authenticated: true,
  }),
  onError: async (error) => {
    console.error(error);
    return { error };
  },
  getPermissions: async () => ["admin"],
  getIdentity: async () => null,
};

// visible-block-start
import { Show } from "@refinedev/mui";
import { usePermissions } from "@refinedev/core";

const ShowPage: React.FC = () => {
  const { data: permissionsData } = usePermissions();
  return (
    <Show
      /* highlight-start */
      canDelete={permissionsData?.includes("admin")}
      deleteButtonProps={{ size: "small" }}
      canEdit={
        permissionsData?.includes("editor") ||
        permissionsData?.includes("admin")
      }
      /* highlight-end */
    >
      <p>Rest of your page here</p>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      authProvider={authProvider}
      dataProvider={customDataProvider}
      resources={[
        {
          name: "posts",
          show: "/posts/show/:id",
          list: "/posts",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route element={<ShowPage />} path="/posts/show/123" />
        <ReactRouter.Route element={<SampleList />} path="/posts" />
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

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).

tsx
setInitialRoutes(["/custom"]);

// visible-block-start
import { Show } from "@refinedev/mui";

const CustomPage: React.FC = () => {
  return (
    /* highlight-next-line */
    <Show resource="posts" recordItemId={123}>
      <span>Rest of your page here</span>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: "/posts",
          show: "/posts/show/:id",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/custom"
          element={
            <div style={{ padding: 16 }}>
              <CustomPage />
            </div>
          }
        />
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

<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.

tsx
import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";

import { Show } from "@refinedev/mui";

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

export const App: React.FC = () => {
  return (
    <Refine
      // highlight-start
      dataProvider={{
        default: dataProvider("https://api.fake-rest.refine.dev/"),
        other: dataProvider("https://other-api.fake-rest.refine.dev/"),
      }}
      // highlight-end
    >
    </Refine>
  );
};

goBack

To customize the back button or to disable it, you can use the goBack property.

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
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
      // highlight-next-line
      goBack={<BackButton />}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: () => (
            <div>
              <p>This page is empty.</p>
              <ShowButton recordItemId="123" />
            </div>
          ),
          show: PostShow,
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/posts/show/:id"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>
          }
        >
          <ReactRouter.Route index element={<PostShow />} />
        </ReactRouter.Route>
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

isLoading

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

tsx
setInitialRoutes(["/posts/show/123"]);
// visible-block-start
import { Show } from "@refinedev/mui";

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

  return (
    <Show
      // highlight-next-line
      isLoading={loading}
    >
      <span>Rest of your page here</span>
    </Show>
  );
};
// visible-block-end

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          show: "/posts/show/:id",
          list: "/posts",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route element={<PostShow />} path="/posts/show/123" />
        <ReactRouter.Route element={<SampleList />} path="/posts" />
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

breadcrumb <GlobalConfigBadge id="core/refine-component/#breadcrumb" />

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

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
import { Show, Breadcrumb } from "@refinedev/mui";

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

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          show: "/posts/show/:id",
          list: "/posts",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route element={<PostShow />} path="/posts/show/123" />
        <ReactRouter.Route element={<SampleList />} path="/posts" />
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

wrapperProps

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

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
import { Show } from "@refinedev/mui";

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

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

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          show: "/posts/show/:id",
          list: "/posts",
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route element={<PostShow />} path="/posts/show/123" />

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.

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";

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

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

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: () => (
            <div>
              <p>This page is empty.</p>
              <ShowButton recordItemId="123" />
            </div>
          ),
          show: PostShow,
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/posts/show/:id"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>
          }
        >
          <ReactRouter.Route index element={<PostShow />} />
        </ReactRouter.Route>
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);

Or, instead of using the defaultButtons, you can create your own buttons:

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
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
      // highlight-start
      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" }} />
        </>
      )}
      // highlight-end
    >
      <span>Rest of your page here</span>
    </Show>
  );
};
// visible-block-end

render(
  <RefineMuiDemo
    resources={[
      {
        name: "posts",
        list: () => (
          <div>
            <p>This page is empty.</p>
            <ShowButton recordItemId="123" />
          </div>
        ),
        show: PostShow,
      },
    ]}
  />,
);

headerButtonProps

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

tsx
setInitialRoutes(["/posts/show/123"]);

// visible-block-start
import { Show } from "@refinedev/mui";
import { Button } from "@mui/material";

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

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

render(
  <ReactRouter.BrowserRouter>
    <RefineMuiDemo
      resources={[
        {
          name: "posts",
          list: () => (
            <div>
              <p>This page is empty.</p>
              <ShowButton recordItemId="123" />
            </div>
          ),
          show: PostShow,
        },
      ]}
    >
      <ReactRouter.Routes>
        <ReactRouter.Route
          path="/posts/show/:id"
          element={
            <div style={{ padding: 16 }}>
              <ReactRouter.Outlet />
            </div>
          }
        >
          <ReactRouter.Route index element={<PostShow />} />
        </ReactRouter.Route>
      </ReactRouter.Routes>
    </RefineMuiDemo>
  </ReactRouter.BrowserRouter>,
);
