Can I have long drop down menus show in shorter table/column format?

I'm sorry if this was written somewhere else in the forums, but I searched and can not find where someone asked about creating a table or columns for drop down menus. Basically I have combined the page and category menus, and my client has TONS of categories under a parent. They don't want one very long menu, but would prefer something like this site:

Can I use the built in Atahualpa menus or do I need to get a plugin to handle this for me?

Thanks for the help!!!
