How To New Tab w/ Sub Menus that Drop Down??

[Budget101]

I've read all of the "New Tab" articles on the site that I can find. I want to know, IS it Possible to create a NEW Tab that allows the user to stay right where they are on the site, no matter which page they are on when they click it, in other words it doesn't GO Anywhere, it just provides a submenu of various links WITH additional drop down submenus once those links are clicked on.

BUT:

Once they click on the New Tab (called SECTIONS) it will display a list of Various sections underneath the navbar tab.

Some of these sub-menus include drop down boxes of additional links.

For Example:

MAIN NAVBAR: CMS | FORUMS | BLOGS | SECTIONS
SUBMENU that appears on Click: FRUIT | VEGGIES | MEATS |
Drop down menu that appears on submenu click: CARROTS
CABBAGE
SQUASH

I've asked in Lynnes article, but so far (a couple weeks later) STILL no answer as to whether it's even Possible to do.
