Sliding Accordion Panels
This is a really simple accordion which uses divs so that the content can use pages created in EverWeb and inserted using iframes.
The example here has all the panels shut on page load. There is an alternative script to have the first panel open on page load.
Open up the panels and find out how to create accordion sliding panels without having to use HTML and CSS to create the panel content.
The MORE section of the Widgetbox website includes a widget to make creating tabs a lot easier.
