If you’re worried about localhost vs. remote after migration then make your links relative.
In the case where you are using the standard wp_nav_menu like;
wp_nav_menu( array(
'menu' => 'test'
));
Filter the HTML from wp_nav_menu to make all the links relative.
add_filter( 'wp_nav_menu', function( $nav_menu, $args ){
// get the current site
$site_url = get_site_url();
// remove from all links
$relative_menu = str_ireplace($site_url, '', $nav_menu);
// return relative menu
return $relative_menu;
});
If you want to always point to a specific URL no matter when the site is located (local or remote) then add custom links to your menu as absolute paths.
