HTML, CSS, WordPress, Widgets API, Transients API
This was by far the most ambitious and most controversial project I have been a part of at UALR. The entire site is composed of individual WordPress sites within a multisite install. Because of this there was no unified navigation theme implemented. The actual menu consists of content originating in a single site within the multisite that then displayed in the dropdown. I got a crash course in the Transients API and the way that WordPress behaves in a multisite. While I am happy with the menu the performance of the menu because it is in a plugin is terrible and will be incorporated into the next template directly.
