You can begin creating the menu by going to Appearance > Menus.
You can set a 2, 3, 4 or 5 column menu by adding the following classes in the CSS Classes field: sohohotel-megamenu-2-col (2 Columns), sohohotel-megamenu-3-col (3 Columns), sohohotel-megamenu-4-col (4 Columns) or sohohotel-megamenu-5-col (5 Columns).
For certain header styles, under each main menu item there are sub titles e.g. Home has welcome below it.
