How to create a new drop down menu with categories

Hey,
I need to create a drop down menu. I create some menus linked with K2 Item. For now everything is ok. Look the picture:

But I want all this menus to reorganize it to 4 colums which colums have a title...
My idea is to organize all trips in 4-5 columns and that columns is the different continents...(like 1 columns with a trips for Asia, 1 for Europe, 1 for America and etc...)
How to get that?

Hi,
go to: Menu Manager: Edit Menu Item then choose Columns [4] in Menu Params (GavickPro) tab - on your main menu position.

Thank you, that's work, but now I want at the top of each column to set the Title for that column...
