I am working on a 1920px-wide site that will be displayed on HDTVs internally at an office. I'd like to place text and other info into (ideally) sidebar blocks, but I'd like for those blocks to be hidden when the page loads. Then, when someone clicks a block's title, that block alone would expand, displaying its content over the primary content area. I have attached an image to illustrate what I mean.
Does anyone here know of a module that can accommodate this type of functionality? If not, any recommendations on how to achieve this would be most appreciated. The sidebar content does not necessarily have to be in blocks.
