I’ve thrown in the towel on trying to get Sifr headings to appear behind my dropdowns. I’d prefer to have plain old text headings and be able to navigate the site thanks very much. Sifr and z-index just don’t want to co-operate with each other. Sifr has caused mucho headaches anytime I’ve tried to use it. I have used it on a lot of sites to do nice headers but I have spent so much time trouble-shooting with it, that the acronym just gives me a bad taste in my mouth now. I’d rather never use it again.
