A breadcrumb displays the current location within a hierarchy. It allows going back to states higher up in the hierarchy. <Breadcrumb> component built with Material UI Breadcrumb components using the useBreadcrumb hook.

:::simple Good to know
You can swizzle this component with the Refine CLI to customize it.
In earlier versions of Refine, <Refine> component had accepted DashboardPage which could be used to add an index page to your app. With the changes in routerProvider API of Refine, DashboardPage is deprecated. You can now define an index route yourself manually by your router package.
In earlier versions, the home icon in the Breadcrumb was created by the DashboardPage, now it is rendered if you define a an action route as / in any one of your resources. It will be rendered with the home icon regardless of the current route. You can also hide the home icon by setting showHome to false.
:::
<Breadcrumb> component uses the Material UI's Breadcrumb component so it can be configured with the breadcrumbProps property.
import { List, Breadcrumb } from "@refinedev/mui";
export const PostList: React.FC = () => {
return (
<List breadcrumb={<Breadcrumb breadcrumbProps={{ separator: "-" }} />}>
...
</List>
);
};
If you have a page with route /, it will be used as the root of the hierarchy and shown in the Breadcrumb with a home icon. To hide the root item, set showHome to false.
import { List, Breadcrumb } from "@refinedev/antd";
export const PostList: React.FC = () => {
return (
<List
// highlight-next-line
breadcrumb={<Breadcrumb showHome={true} />}
>
...
</List>
);
};
If your routes has additional parameters in their paths, you can pass the meta property to the <Breadcrumb> component to use them while creating the paths and filling the parameters in the paths. By default, existing URL parameters are used. You can use meta to override them or add new ones.
import { List, Breadcrumb } from "@refinedev/mui";
export const PostList: React.FC = () => {
return (
<List
// highlight-next-line
breadcrumb={<Breadcrumb meta={{ authorId: "123" }} />}
>
...
</List>
);
};
If you don't want to show the resource icons on the breadcrumb, you can set hideIcons to true.
import { List, Breadcrumb } from "@refinedev/mui";
export const PostList: React.FC = () => {
return (
<List breadcrumb={<Breadcrumb hideIcons />}>...</List>;
);
};
