This is a tutorial by Codyhouse.A bold navigation that slides in when active, replacing the current content in a 3D space.
Bear in mind, though, it doesn’t have to be the “main” navigation. You could have, for example, a product gallery and you’d like to create a smooth transition while switching from one product category to the other.
The interesting thing is; when you select a new category, you switch the content in the background, then move it back to the original position, hiding the navigation.
