React Router with - Ant Design Sider: how to populate content section with components for relevant menu item

The better solution is using React Router <Link> to make each menu item link to a specific path, and then in the content, using <Switch> to render the corresponding component. Here's the doc: React router

Render With React Router

<Router>
  <Layout style={{ minHeight: "100vh" }}>
    <Sider
      collapsible
      collapsed={this.state.collapsed}
      onCollapse={this.onCollapse}
    >
      <div />
      <Menu theme="light" defaultSelectedKeys={["1"]} mode="inline">
        <Menu.Item key="1">
          // Add a react router link here
          <Link to="/password-forget-form">
            <Icon type="fire" />
            <span>Next item</span>
          </Link>
        </Menu.Item>
        <Menu.Item key="2">
          // Add another react router link
          <Link to="/next-item">
            <Icon type="fire" />
            <span>Next item</span>
          </Link>
        </Menu.Item>
      </Menu>
    </Sider>
    <Layout>
      <Header style={{ background: "#fff", padding: 0 }} />
      <Content style={{ margin: "0 16px", background: "#fff" }}>
        <div style={{ padding: 24, background: "#fff", minHeight: 360 }}>
          // Render different components based on the path
          <Switch>
            <Route path="/password-forget-form">
              <PasswordForgetForm />
            </Route>
            <Route path="/next-item">
              <Another component to render in the content div />
            </Route>
          </Switch>
        </div>
      </Content>
    </Layout>
  </Layout>
</Router>;

Render With Menu Keys

App.js

import React, { useState } from "react";
import { Layout } from "antd";
import Sider from "./Sider";
import "./styles.css";

const { Content } = Layout;
export default function App() {
  const style = {
    fontSize: "30px",
    height: "100%",
    display: "flex",
    alignItems: "center",
    justifyContent: "center"
  };

  const components = {
    1: <div style={style}>Option 1</div>,
    2: <div style={style}>Option 2</div>,
    3: <div style={style}>Option 3</div>,
    4: <div style={style}>Option 4</div>
  };

  const [render, updateRender] = useState(1);

  const handleMenuClick = menu => {
    updateRender(menu.key);
  };

  return (
    <div className="App">
      <Layout style={{ minHeight: "100vh" }}>
        <Sider handleClick={handleMenuClick} />
        <Layout>
          <Content>{components[render]}</Content>
        </Layout>
      </Layout>
    </div>
  );
}

Sider.js

import React from "react";
import { Menu, Layout, Icon } from "antd";

const { SubMenu } = Menu;

export default function Sider(props) {
  const { handleClick } = props;
  return (
    <Layout.Sider>
      <Menu theme="dark" mode="inline" openKeys={"sub1"}>
        <SubMenu
          key="sub1"
          title={
            <span>
              <Icon type="mail" />
              <span>Navigation One</span>
            </span>
          }
        >
          <Menu.Item key="1" onClick={handleClick}>
            Option 1
          </Menu.Item>
          <Menu.Item key="2" onClick={handleClick}>
            Option 2
          </Menu.Item>
          <Menu.Item key="3" onClick={handleClick}>
            Option 3
          </Menu.Item>
          <Menu.Item key="4" onClick={handleClick}>
            Option 4
          </Menu.Item>
        </SubMenu>
      </Menu>
    </Layout.Sider>
  );
}
