Try this this will add URL

wp_nav_menu( array( 'theme_location' => 'header-menu','menu_class' => 'drop', 'container' => 'nav', 'link_before' => '<span></span>') );

If you want it this way url

 wp_nav_menu( array( 'theme_location' => 'header-menu','menu_class' => 'drop', 'container' => 'nav', 'link_before' => '<span>', 'link_after' => '</span>') );

Answer 3

Is this what you mean? You may have to explain a little further, but this is how you'd add some additional values to wp_nav_menu.

wp_nav_menu(array(
            'MyItem' => 'My Value',                 // <--new item
            'MyotherItem' => 'My Other Value',      // <--other new item
            'menu' => 'Main Menu',
            'theme_location' => 'Main Menu',
            'container' => null,
            'container_class' => '',
            'menu_id' => 'header-menu',
            'menu_class' => '',
            'before' => '<span class="text1">',
            'after' => '</span><span class="text2"><a href="">' . the_title($post->ID) . '</a></span>',
));
