Nothing's Perfect

The purpose of the website, of course, is to highlight the storytellers and their stories. I would like to have the site published sooner rather than later. There are some issues I'd like to see resolved. The conclusion I am reaching is that these issues can be addressed over time. Waiting until things are just so could delay publication indefinitely. 

The main issue is navigation on the PODCAST page.

What I'd like to see happen is multiple child pages, like this:

PODCAST
   2012
      Dear Diary
         Story 1
         Story 2
         Story 3
         etc
      Rites of Passage
         Story 1
         Story 2
         Story 3
         etc
      I Got Lucky
         Story 1
         Story 2
         Story 3
         etc
      Forgiveness
         Story 1
         Story 2
         Story 3
         etc

So that hovering over the PODCAST menu would reveal the years (2012, 2013, 2014, 2015 etc individually). Hovering over a year would then reveal the themes for that year. Selecting a theme would then display to the user all of the stories for that theme.

Squarespace support's answer this question is that it is not natively supported, but is possible using CSS.

I'm hoping to find someone who can help code said CSS. For now, I'll call this the first release knowing that new features, such as the one I describe above, will be added over time.
