    wp_nav_menu(
        array(
            'theme_location'  => 'social-menu',
            'container'       => 'nav',
            'container_id'    => 'social',
            'container_class' => 'social-icon',
            'menu_id'         => 'menu-social-items',
            'menu_class'      => 'social-menu',
            'depth'           => 1,
            'fallback_cb'     => '',
                        'link_before'     => '<i class="social_icon fa"><span>',
                        'link_after'      => '</span></i>'
        )
      );

            'menu_id'         => 'menu-social-items',
            'menu_class'      => 'social-menu',
            'depth'           => 1,
            'fallback_cb'     => '',
                        'link_before'     => '<i class="social_icon fa"><span>',
                        'link_after'      => '</span></i>'
