category and page

Greeting,

am using this function into my function.php to display category in page

`//add page category abd tag{
function add_taxonomies_to_pages() {
register_taxonomy_for_object_type( ‘category’, ‘page’ );
register_taxonomy_for_object_type( ‘post_tag’, ‘page’ );
}
add_action( ‘init’, ‘add_taxonomies_to_pages’ );
//}

However, when am creating a category into the page section, the same category is created into the post section.

I’d like to know if there is a solution to split those category ?

am using get_categories to display category in front page, but i saw on google that get_categories() have no filter with post_type page or post.

any idea ?
BR
