Note

In MainPage.xaml.cs, we can see that the “IsPresented” property has been set to false every time. If we set this property to true, then the menu will be unnecessarily visible to the item content and for making it hidden, we have to click on the item page.

So, in general scenario, we want the menu to be hidden just after selecting the menu item.

You can check the same output on Android Emulator.
