Highlighting some of the truly innovative stuff here on Freshblog, and road-testing a new hack at the same time, I've added in a horizontal menu underneath the page header. I looked at a couple of these, in an effort to help Chaim get one off the ground at Life of Rubin. We ran into an MSIE compatibility error with the first effort, but the menu at Alsacreations seems to be browser-proof and was pretty easy to install & customise. Chaim's implementation turned out even slicker than the implementation here, I think!
The installation is pretty straightforward. There's a pre-formed stylesheet for your template head, and a chunk of HTML that goes where you want the buttons to appear. I ran into an issue with my existing CSS, and had to make some changes to the code as provided. It took some work w/ the CSS at Freshblog to make sure that the formatting only applied to the buttons under the header, and not to all of the lists on the page, but formatting the list in its own class seems to work, and we're good to go. Check out the basic code at Alsacreations, and see whether it will work for you!
