# Render Menu from the backend

{% tabs %}
{% tab title="VITE(TS)" %}
Mantis 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: <https://github.com/phoenixcoded20/mock-data-api-nextjs>

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
...

import { fetcher } from 'utils/axios';

// types
import { MenuProps, NavItemType } from 'types/menu';

export const endpoints = {
  key: 'api/menu',
  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. Create Menu File
   1. Add file **menu.tsx** in `src/menu-items`, and copy code from `dashboard.tsx` `(src/menu-items/)`. Set icons and local files according to the API response.
3. Open the file **index.tsx** *`(`*`src/layout/Dashboard/Drawer/DrawerContent/Navigation/index.tsx`*`)`*, and add the below code of the line.

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

```typescript

import { useLayoutEffect, useState } from 'react'
...

import menuItem from 'menu-items';
import { MenuFromAPI } from 'menu-items/menu';
import { useGetMenu, useGetMenuMaster } from 'api/menu';
...

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

export default function Navigation() {

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

let dashboardMenu = MenuFromAPI();

useLayoutEffect(() => {
    const isFound = menuItem.items.some((element) => {
      if (element.id === 'group-dashboard') {
        return true;
      }
      return false;
    });

    if (menuLoading) {
      menuItem.items.splice(0, 0, dashboardMenu);
      setMenuItems({ items: [...menuItem.items] });
    } else if (!menuLoading && dashboardMenu?.id !== undefined && !isFound) {
      menuItem.items.splice(0, 1, dashboardMenu);
      setMenuItems({ items: [...menuItem.items] });
    } else {
      setMenuItems({ items: [...menuItem.items] });
    }
    // eslint-disable-next-line
  }, [menuLoading]);
```
