I have come to appreciate the amazing versatility of the Atahualpa theme. I am hoping someone can advise me how to implement a 2 -tiered navigation structure. An example of this can be found at http://www.portsmouthhistory.org (note that the second tier does not display until you click one of the pages that is not the home page).
I am guessing that there may be a plugin for this, and if so, is it recommended (or if there are several, which are recommended). That said, I have googled around a bit and not seen anything that was quite like what I am looking for.
Or - is there a solution using jQuery or some other tools (which I am not familiar with, it could at least find someone to code up for me). A major goal is to implement it in such a way that updates to the theme don't require re-programming.
