wp_nav_menu adding a class to a menu item

Problem

I have a menu which uses wp_nav_menu and I need to add a class to the first item because my menu items have a left border on them.  I don’t want the first item to show a border.

 

Solution

WordPress is just so easy to use.  This may not have been in previous versions, but as of 3.3.1 at least there is a way to add a class to each menu item through the interface.  Go to Appearnace->Menus.  At the top, click on Screen Options and check “CSS Classes”.  Now you can expand a menu item and add a class in there.
