After searching on google, I was even more lost than where I started.

Simply put, I have a html web page.

In the navigation, I wish to add drop down menus for similar-related pages under one main category.

Wondering if anyone can point me to a resource or anything? Hopefully I can get some insight!

Thanks

If you have php website then i can surely help you as i have made a drop down menu in WP.

No need for javascript or server-side code, this can be achieved with html and css:
example:

thanks :D

the suckerfish menu is nice, but I prefer the superfish menu. jQuery adds a nice touch. Try googling it.
