# Render Menu from the backend

Able Pro is already rendering the menu from the backend. The dashboard menus (Default, Analytics) are rendered via the back end.

You can check the Fack backend API here that we used to render the menu: 

{% embed url="<https://github.com/phoenixcoded20/mock-data-api-nextjs>" %}

{% tabs %}
{% tab title="NEXT  (TS)" %}
To add a menu from the backend, you can follow the steps below:

1. Open the file **`menu.ts`** *(src/api/menu.ts)*, and edit the API URL in the **useGetMenu** function

{% code title="src/api/menu.ts" %}

```typescript
const endpoints = {
  key: 'api/menu',
  master: 'master',
  dashboard: '/dashboard' // server URL
};

export function useGetMenu() {
  const { data, isLoading, error, isValidating } = useSWR(endpoints.key + endpoints.dashboard, fetcher, {
    revalidateIfStale: false,
    revalidateOnFocus: false,
    revalidateOnReconnect: false
  });

  const memoizedValue = useMemo(() => {
    let updatedMenu = data?.dashboard;

    if (updatedMenu && Array.isArray(updatedMenu.children) && updatedMenu.children.length > 0) {
      updatedMenu = {
        ...updatedMenu,
        children: updatedMenu.children.map((group: NavItemType) => {
          if (Array.isArray(group.children)) {
            return {
              ...group,
              children: [...group.children, staticMenuItem]
            };
          }
          return group;
        })
      };
    }

    return {
      menu: updatedMenu as NavItemType,
      menuLoading: isLoading,
      menuError: error,
      menuValidating: isValidating,
      menuEmpty: !isLoading && !data?.length
    };
  }, [data, error, isLoading, isValidating]);

  return memoizedValue;
}
```

{% endcode %}

2. Add a file **`menu.tsx`** in the src/menu-items, and copy the code from **`dashboard.tsx`** (src/menu-items/). Set icons and local files according to the API response.
3. Open the file **`index.tsx`** *(*&#x73;rc/layout/Dashboard/Drawer/DrawerContent/Navigation/index.ts&#x78;*)*, and add the code below the line.

{% code title="src/layout/Dashboard/Drawer/DrawerContent/Navigation/index.tsx" %}

```typescript
import { useGetMenu } from 'api/menu';
import menuItem from 'menu-items';
import { MenuFromAPI } from 'menu-items/dashboard';

function isFound(arr: any, str: string) {
  return arr.items.some((element: any) => {
    if (element.id === str) {
      return true;
    }
    return false;
  });
}

// ==============================|| DRAWER CONTENT - NAVIGATION ||============================== //

export default function Navigation() {
  const { menuLoading } = useGetMenu();
  
  const [menuItems, setMenuItems] = useState<{ items: NavItemType[] }>({ items: [] });

  const dashboardMenu = MenuFromAPI();
  useLayoutEffect(() => {
    if (menuLoading && !isFound(menuItem, 'group-dashboard-loading')) {
      menuItem.items.splice(0, 0, dashboardMenu);
      setMenuItems({ items: [...menuItem.items] });
    } else if (!menuLoading && dashboardMenu?.id !== undefined && !isFound(menuItem, 'group-dashboard')) {
      menuItem.items.splice(0, 1, dashboardMenu);
      setMenuItems({ items: [...menuItem.items] });
    } else {
      setMenuItems({ items: [...menuItem.items] });
    }
    // eslint-disable-next-line
  }, [menuLoading]);

  ...
}
```

1. Open the file **`menu.js`** *(src/api/menu.js)*, and edit the API URL in the **useGetMenu** function

    if (element.id === str) {
      return true;
    }
    return false;

}
