I am working on this site: http://www.careace.net.
The site basically has 3 devices filled with contents such as downloads, news, reviews, etc. Now the devices (Omnia, Epix, Blackjack) are tags and the contents are in categories.
On the left sidebar is the Category navigation. Now I hope to make a dropdown box that is tag-specific. For example, I will have an Omnia tag, and then a dropdown box beneath it with all the categories related to that tag (i.e. download, review).
Does anyone have experience with this?
