Fetch menu items

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

Hi @ctsz. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To dynamically create menu items via your API in a Refine application, you can use the useMenu hook. This hook allows you to fetch and render menu items based on the resources defined in your <Refine> component. Here’s a step-by-step guide to help you achieve this: 1. Set Up Your Resources: Ensure that your resources are defined in the <Refine> component. These resources will be used to generate the menu items. 2. Use the useMenu Hook: This hook will fetch the menu items based on the resources. You can then map these items to create your custom menu. 3. 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 useMenu hook. Here’s an example of how you can create a custom menu using the useMenu hook:

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>
  );
};

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. For more details, you can refer to the [useMenu documentation](https:// ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
