I started tinkering with a new Drupal theme that has drop down nav menus that I found here: http://thanhsiang.org/faqing/node/88#comment-522. After rearranging my menu system, I was able to get the drop downs to work correctly & I also connected the menuing system to the Drupal taxonomy module which I also recently configured.
So far I've setup two taxonomies, the first I call 'subject' with categories like: life, family, travel, running, local, gaming, politics, tech, and research. The second taxonomy I created is called 'content types' and has just two types in it, video and images.
Then I assigned one or more of these two sets of intersecting taxonomy categories to each content item on my site. The idea here is to allow a user to click on a "content type" (e.g. videos) that they might want to see & that will give them a list of all content with that content type.
