I want to add an image that is to the right of a link in the custom menus if they have an external link (_blank). I've tried a few things with the Walker but not having much success. I have multiple menus and trying to make this as easy as a 'click' for the end user. Thanks much!
Added this after the walker
wp_nav_menu( array('menu_class' => 'openLink', 'link_after' => '<div class="openLinkImg"></div>', 'walker'=> new MFC_Walker_Nav_Menu() ) );
I had added 'openLink' to use as a trigger.
