[Menu plugin?]

Hi!

My first post here.

I am looking for a plugin, or any other way to give me a menu that looks like this:

The upper row is pages and the secondrow is subpages for that page. It can also be categories and subcategories.

If I am on page one I want the second row to show the titles for subpages to page one, if I´m on page 2 I want the second row to show the titles for subpages to page two and so on.

Is there a plugin or any other easy way, or hard if that is necessary to accomplish this.

Thanx in advance
