        HStack {
            Menu("Menu") {
                Button("menu1", action: {
//                    Webview(url: "https://readmorejoy.com")
                })
                Button("menu2", action: {})
                Button("menu3", action: {})
            }
        }
    }
}

Here it is

struct ContentView: View {
    @State private var urlString = "https://readmorejoy.com"   // << initial !!

    var body: some View {
        Webview(url: urlString)     // << use !!
        HStack {
            Menu("Menu") {
                Button("menu1", action: {
                    self.urlString = "https://readmorejoy.com"   // << update !!
                })
                Button("menu2", action: {})
                Button("menu3", action: {})
            }
        }
    }
}
