Subnavigaton/Drop Down List

Thank-you for any help you can provide. I have been through many posts and widgets and plugins. I am new and I am not sure which one would be best. On my navigation, when I create a page, I need to be able to create a page separate but a part of that one page. Which means I also need to have a drop down list when the cursor hovers over the navigation name. Such as a “Basics” and when that is hovered over a drop down list of separate pages for example: “Make Tea”, “Make Decoction”, so on and so forth. I am trying to be specific to not to waste anyone’s one’s time, nor mine. Been working on trying to get this going for three months. I really desperately need some help. Thank-you very much.
