QUESTION Parent page not in the menu?

[smdp-1971]

Is there a way to display child pages if a parent page is not in the menu, using?

PHP Code:

<?php get_onepage_navigation();?>

<?php get_i18n_navigation(); ?>

Example:

Code:

Parent Page name (Not in menu)
- Child page name 1 (Add to the menu)
- Child page name 2 (Add to the menu)

Thanks!
