useMenu
useMenu is used to get menu items derived from the resources. These items include a link to the dashboard page (if it exists) and links to the user-defined resources (passed as children to <Refine>).
This hook can also be used to build custom menus, including multi-level support. <Sider/> components inside @pankod/refine-antd, @pankod/refine-mui, @pankod/refine-chakra-ui and, @pankod/refine-mantine packages are using this hook as a base for their menus.
const { selectedKey, menuItems, defaultOpenKeys } = useMenu();
menuItemsis a list of style agnostic menu items. Each of them has a key.selectedKeyis the key of the resource user is viewing at the moment. Its inferred from the route.defaultOpenKeysis the array with the keys of default opened menus.
useMenu hooks exported from @pankod/refine-antd and @pankod/refine-mui packages are now deprecated and will be removed. Please use useMenu from @pankod/refine-core.
Usage
If you are using @pankod/refine-antd, @pankod/refine-mui, @pankod/refine-chakra-ui or @pankod/refine-mantine as a UI framework integration, you can find out more info about how their <Sider/> components are created and how to create a custom one by following their guides.

Creating a Menu
We will show you how to use useMenu to create a simple menu for your refine application.
http://localhost:3000We created <Layout> with a header with a logo and a list of links to all menu items (resources). The links are clickable and will navigate to the corresponding resource. To do this, we used the useMenu hook to get the menu items from the <Refine/> and the useRouterContext hook to get the <Link/> component from the router provider. Also useNavigation hook can be used to navigate between routes.
children is the content of the layout. In our case, it is the content of the Page components.
After creating the <Layout/> component, we can use it in our application. We need to pass it to the <Refine/> component as a prop.
Multi Level Menus
useMenu hook comes out of the box with multi level menu support, you can render menu items recursively to get a multi level menu.
Update your resources in <Refine/> with parentName to nest them inside a label.
import { Refine } from "@pankod/refine-core";
import routerProvider from "@pankod/refine-react-router-v6";
import dataProvider from "@pankod/refine-simple-rest";
import { Layout } from "components/layout";
const API_URL = "https://api.fake-rest.refine.dev";
const App: React.FC = () => {
return (
<Refine
routerProvider={routerProvider}
dataProvider={dataProvider(API_URL)}
resources={[
{
name: "CMS",
},
{
name: "posts",
parentName: "CMS",
list: () => <div>dummy posts page</div>,
},
{
name: "categories",
parentName: "CMS",
list: () => <div>dummy categories page</div>,
},
]}
Layout={Layout}
/>
);
};
export default App;
Now you can update your <Layout/> to support multi level rendering with following code:
import React from "react";
import {
useMenu,
LayoutProps,
useRouterContext,
useRefineContext,
ITreeMenu,
} from "@pankod/refine-core";
export const Layout: React.FC<LayoutProps> = ({ children }) => {
const { menuItems, selectedKey } = useMenu();
const { Link } = useRouterContext();
const renderMenuItems = (items: ITreeMenu[]) => {
return (
<>
{items.map(({ name, label, icon, route, children, list }) => {
if (!list) {
return (
<li key={label}>
<span>{label ?? name}</span>
{children ? renderMenuItems(children) : null}
</li>
);
}
const isSelected = route === selectedKey;
return (
<li key={label}>
<Link
to={route}
style={{
fontWeight: isSelected ? "bold" : "normal",
}}
>
{icon}
<span>{label ?? name}</span>
</Link>
</li>
);
})}
</>
);
};
return (
<div>
<div>
<Link to="/">
<img
src="https://refine.dev/img/refine_logo.png"
alt="Logo"
/>
</Link>
<ul>
{hasDashboard && (
<li>
<Link
to="/"
style={{
fontWeight:
selectedKey === "/" ? "bold" : "normal",
}}
>
<span>Dashboard</span>
</Link>
</li>
)}
{renderMenuItems(menuItems)}
</ul>
</div>
<div>{children}</div>
</div>
);
};
