Fetch menu items

I'm struggling to create menu items dynamically via our API. Is there any specific way to handle this case?

----------------------
To dynamically create menu items via your API in a Refine application, you can use the useMenuuseMenu hook. This hook allows you to fetch and render menu items based on the resources defined in your

<Refine>

<Refine>

component. Here’s a step-by-step guide to help you achieve this:

Set Up Your Resources: Ensure that your resources are defined in the
```
<Refine>
```
```
<Refine>
```
component. These resources will be used to generate the menu items.
Use the useMenuuseMenu Hook: This hook will fetch the menu items based on the resources. You can then map these items to create your custom menu.
Fetch Data from API: If you need to fetch additional data from your API to create a dynamic secondary menu, you can do so within your component and then integrate it with the useMenuuseMenu hook.

Here’s an example of how you can create a custom menu using the useMenuuseMenu hook:

```jsx
import React, { useEffect, useState } from "react";
import { useMenu, LayoutProps, ITreeMenu } from "@refinedev/core";
import { Link } from "react-router-dom";

const Layout: React.FC<LayoutProps> = ({ children }) => {
const { menuItems, selectedKey } = useMenu();
const [dynamicMenuItems, setDynamicMenuItems] = useState<ITreeMenu[]>([]);

useEffect(() => {
// Fetch additional menu items from your API
fetch("https://api.yourservice.com/menus")
.then(response => response.json())
.then(data => {
setDynamicMenuItems(data);
});
}, []);

const renderMenuItems = (items: ITreeMenu[]) => {
return (
<>
{items.map(({ key, name, label, icon, route }) => {
const isSelected = key === selectedKey;
return (
<li key={name}>
<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>{renderMenuItems([...menuItems, ...dynamicMenuItems])}</ul>
</div>
<div>{children}</div>
</div>
);
};

import { Refine } from "@refinedev/core";
import routerProvider, { NavigateToResource } from "@refinedev/react-router-v6";
import dataProvider from "@refinedev/simple-rest";
import { BrowserRouter, Routes, Route, Outlet } from "react-router-dom";

const API_URL = "https://api.fake-rest.refine.dev";

const App: React.FC = () => {
return (
<BrowserRouter>
<Refine
dataProvider={dataProvider(API_URL)}
routerProvider={routerProvider}
resources={[
{
name: "posts",
list: "/posts",
},
{
name: "categories",
list: "/categories",
},
]}
/>
</BrowserRouter>
);
};

In this example:
- The

useMenu` hook is used to get the initial menu items based on the resources.

An additional API call is made to fetch dynamic menu items.
Both static and dynamic menu items are rendered together.
