@kteschmitt: Ok here is the code. You just need to create empty functions.php file in your child theme and then add the following code.
<?php
/**
* Catch Box Child Theme functions and definitions
*
*/
/**
* Header Menu
*
* @since Catch Box 2.5
*/
function catchbox_header_menu() { ?>
<nav id="access" role="navigation">
<h3 class="assistive-text"><?php _e( 'Primary menu', 'catchbox' ); ?></h3>
<?php /* Allow screen readers / text browsers to skip the navigation menu and get right to the good stuff. */ ?>
<div class="skip-link"><a class="assistive-text" href="#content" title="<?php esc_attr_e( 'Skip to primary content', 'catchbox' ); ?>"><?php _e( 'Skip to primary content', 'catchbox' ); ?></a></div>
<div class="skip-link"><a class="assistive-text" href="#secondary" title="<?php esc_attr_e( 'Skip to secondary content', 'catchbox' ); ?>"><?php _e( 'Skip to secondary content', 'catchbox' ); ?></a></div>
<?php /* Our navigation menu. If one isn't filled out, wp_nav_menu falls back to wp_page_menu. The menu assiged to the primary position is the one used. If none is assigned, the menu with the lowest ID is used. */ ?>
<?php
if ( has_nav_menu( 'primary', 'catchbox' ) ) {
$args = array(
'theme_location' => 'primary',
'container_class' => 'menu-header-container',
'items_wrap' => '<ul class="menu">%3$s</ul>'
);
wp_nav_menu( $args );
}
else {
echo '<div class="menu-header-container">';
wp_page_menu( array( 'menu_class' => 'menu' ) );
echo '</div>';
} ?>
</nav><!-- #access -->
<?php if ( has_nav_menu( 'secondary' ) && is_page(array('375', '333', '327', '381', '335' ) ) ) {
// Check is footer menu is enable or not
$options = catchbox_get_theme_options();
if ( !empty ($options ['enable_menus'] ) ) :
$menuclass = "mobile-enable";
else :
$menuclass = "mobile-disable";
endif;
?>
<nav id="access-secondary" class="<?php echo $menuclass; ?>" role="navigation">
<h3 class="assistive-text"><?php _e( 'Secondary menu', 'catchbox' ); ?></h3>
<?php /* Allow screen readers / text browsers to skip the navigation menu and get right to the good stuff. */ ?>
<div class="skip-link"><a class="assistive-text" href="#content" title="<?php esc_attr_e( 'Skip to primary content', 'catchbox' ); ?>"><?php _e( 'Skip to primary content', 'catchbox' ); ?></a></div>
<div class="skip-link"><a class="assistive-text" href="#secondary" title="<?php esc_attr_e( 'Skip to secondary content', 'catchbox' ); ?>"><?php _e( 'Skip to secondary content', 'catchbox' ); ?></a></div>

</nav>
<?php }
