Ionic2 如何隐藏侧菜单栏同一页的菜单项。在离子2中

在app.component.ts中，我添加了菜单项的所有页面，当主页打开时，我想从侧菜单栏隐藏主菜单项，所有页面都是如此。我试图使用类名来隐藏，但它会影响所有的菜单项css。请给我解决方案：

 constructor(public platform: Platform, public statusBar: StatusBar, public splashScreen: SplashScreen) {
      this.initializeApp();

      this.pages = [
                      { title: 'Home', component: HomePage, icon:'home' },
                      { title: 'Order History', component: OrderHistory, icon:'timer' },
                      { title: 'Profile', component: Profile, icon:'person' }
                    ];
     }

    openPage(page) {
                    console.log("open Menu");
                    // Reset the content nav to have just this page
                    // we wouldn't want the back button to show in this scenario
                    this.nav.setRoot(page.component);   
    }
