Horizontal sub-menu display [instead of dropdown]

i have a page menu bar with only 4 items in it. only the 4th item has submenu items associated with it

i don't like the vertically stacked dropdown menu for this site. i can think of three different ways to solve this but don't know how to make any of them happen. any ideas?

1. the dropdown submenu for the fourth item in the page menu bar could cause a second horizontal array of submenu items to appear just below the main navigation bar
(like the one that appears if you roll over 'join us' in the main menu on this page http://www.seiu775.org/)

2. rolling over the 'weddings' item in the main menu could cause other items to appear in the main page menu bar to the right of the 'weddings' item -- by somehow setting a condition for those menu items to be visible or invisible.

or

3. a second page menu bar, separate from the main page menu bar, could be loaded with the list of pages that i want to appear when 'weddings' is rolled over, and made to be visible only on rollover of that item. which i guess would look pretty much the same as option 1, but in this case they would technically be other top-level pages that would just appear in a separate menu bar.

if anybody knows how to make any of these ideas work, please let me know.

thanks
