Adding a class (arrows) to main menu links that have children?
I have two, very basic css dropdowns in my menu. I want to be able to add an arrow next to the dropdowns like shown below.
What I want to do is basicly use wp_nav_menu's 'after' argument, only if the item has a submenu. I'm guessing I need to add a filter but I have no idea how that works. It would be great if someone could point me in the right direction.
