php - WP Twenty Twelve ナビゲーション ディスプレイ

Question

デフォルトの Twenty Twelve Wordpressテーマのサブナビゲーション リンクをラッパー/コンテナ上に表示するにはどうすればよいですか?

header.php:

<nav id="site-navigation" class="main-navigation" role="navigation">
    <h3 class="menu-toggle"><?php _e( 'Menu', 'twentytwelve' ); ?></h3>
        <a class="assistive-text" href="#content" title="<?php esc_attr_e( 'Skip to content', 'twentytwelve' ); ?>"><?php _e( 'Skip to content', 'twentytwelve' ); ?></a>
        <?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu_class' => 'nav-menu' ) ); ?>
</nav>
