Okay, I followed your advice and downloaded the CSS Horizontal Dropdown Menu With jquery script. It uploaded easily. But now things are even worse. Not only are there buttons that probably looked good with the original template...but not with Sheffield Blue...stretched across the screen, and I don't know how to change them, but also I can't seem to get the headers or categories to come out right.
Instead of the first category showing up as Fiction, it still shows up as Home with Fiction listed beneath it, and some category names that are obviously from the tpl_mega_menu.php file. I don't dare try to remove them...I've already had to reinstall the .bak files way too many times already.
The second category does show up as Non-Fiction, though I'm not sure why it's all-caps instead of the upper/lowercase I entered. Not a big deal as long as it does what I want it to do. But then all the categories I want to use as headers show up beneath that, and they shouldn't...it should only show the Non-Fiction subcategories that I've entered so far.
The third category shows up properly as Science, with more category names from the tpl_mega_menu.php file listed beneath it.
The fourth category shows up properly as Medicine, but has nothing beneath it.
The fifth category shows up as My Account, and the sixth category shows up as Shopping Cart...even though I tried to change those to History and Erotica.
This isn't what I wanted at all, but I don't know how to make it look the way I want; it seems to bounce back and forth between multiple files, and every time I try to change something, I get a blank white page and have to reinstall the .bak file. I've learned a lot about php through installing and maintaining 8 other shopping carts...but I've never worked with this kind of thing before, and I just don't know what to do.
Ideally I want the header to look like this:
Fiction Non-Fiction Fine Arts History Medicine Science Erotica (which will be routed to another site entirely)
with the subcategories I've specified so far (and more to come) listed beneath each of those.
And ideally I'd like to get rid of the brown buttons, and fit these inside the pretty blue (now teal) Sheffield header ribbon.
Can someone please help me with this? :-} I'm trying to learn...I really am...but I'm way over my head, and not ashamed to admit it.
