Rberinger and I worked on this one. See it here: SectionUI
This template changes the UI of sections on a page; for now, the only available option is a "tabs" interface, similar to the Tab/Accordion template, though we will add additional styles if demand warrants. The difference in this template is that it works with the existing contents of the page, not requiring tab names or content to be passed to the template or pulled in from elsewhere. That means you can just create a page normally, then add this template and *voila*: it will look different. As a bonus, the sections can be edited directly inside the new UI (e.g., you can edit a tab section inside the tab.)
This idea for this originated from two places: first, a challenge from crb to make existing sections on a page hideable. After figuring this out, it occurred to me that the foundation had been built to manipulate section appearance arbitrarily. Second, I thought of a request from buzz_burrowes to make a single page present as tabs. Rberinger gamely signed on to the effort and we banged out this template.
So here we are. We hope that this is either useful unto itself, or perhaps the starting point for some other good stuff, or if nothing else an interesting bit of jQuery coding. Feedback, as always, is welcome.
