You are confusing Windows Phone 8.1 runtime and Silverlight applications.
Windows Phone 8.1 runtime will have those menus, Silverlight won't.
See Rob's detailed explanation here: MSDN blog: Why can’t I create an app package?

To build on Chubosaurus's answer, the following project types in Visual Studio use the following runtimes.
- "Windows Phone 8.0" - Silverlight
- "Windows Phone 8.1" - WinRT
- "Windows Phone Silverlight 8.1" - Silverlight
For this reason Visual Studio currently has no upgrade path from "Windows Phone 8.0" to "Windows Phone 8.1", which causes a lot of dev confusion.
