I am the webmaster for a non-profit organization. The website currently has an expanding nav menu done with JS. The menu items expand only once (to a second level).
The organization wants to change the nav so it goes to a third level. I've found scripts that will do that, but I've seen a couple of comments that went something like "that's [multi-level navigation] old school" and "people are still using multilevel drop down menus?"
Opinions, please on why or why not I should consider multi-level menus and what the alternatives are.
I think there's a big decrease in ease of use going from one-level hover navigation to two-level hover navigation. Its really annoying when the menu disappears because you moved your mouse diagonally over a bit of page that isn't in the menu.
