Answer 1

My solution:

$defaults = array(
    'theme_location'  => '',
    'menu'            => '',
    'container'       => '',
    'container_class' => '',
    'container_id'    => '',
    'menu_class'      => '',
    'menu_id'         => '',
    'echo'            => false, // param important
    'fallback_cb'     => 'wp_page_menu',
    'before'          => '',
    'after'           => '',
    'link_before'     => '',
    'link_after'      => '',
    'items_wrap'      => '',
    'depth'           => -1,
    'walker'          => ''
);

ob_start();
echo preg_replace( '#]+>#', '
', wp_nav_menu( $defaults ) );
$mainNav = ob_get_clean();

// In the page :
echo $mainNav;
