I have a hierarchial menu that is two levels deep. It allows the user to pick from a large number of different categories, which in turn have subcategories.
It is implemented as two screens with the first one displaying the top-level categories and clicking one of these takes the user to a similar screen with the subcategories, as shown in the screenshots.
My problem is, I need some subtle, but clear way to indicate to the user where he/she is in the flow, preferrably with a link to go back to the top-level (it can also be done with the back button)
I tried some different ways, including the breadcrumbs shown in the screenshots.
Is there a common, best-practice-ish way of doing this? If so, how do I make it pretty and easy?
