Contact Form 7 - how to add several number fields dynamically - contact-form-7

Question

I am currently working on a web project where users should be able to have a list of brochures (list comes from custom post type) and enter the amount they would like to order individually for each of them via a simple contact form. My idea was to generate a dynamic list of number fields with the 'wpcf7_form_tag_data_option' hook like in this article:
Dynamicly populate Contact form 7 input fields with current user info when logged in in Wordpress website
So if i am using the select or checkbox field type within contact form 7:
[select anzahlKataloge data:brochures]
or
[checkbox anzahlKataloge data:brochures]
and functions.php:
add_filter('wpcf7_form_tag_data_option', function($n, $options, $args) {
if (in_array('brochures', $options)){
$query = new WP_Query(
array( 'orderby' => 'date', 'order' => 'DESC', 'posts_per_page' => '100', 'post_type' => 'prospekte')
);
while($query->have_posts()) : $query->the_post();
$title = get_the_title();
$brochures[] = $title;
endwhile;
return $brochures;
}
return $n;
}, 10, 3);
It generates the select or checkbox list just fine but i would actually need it to work with the number field type:
[number anzahlKataloge data:brochures]
or with text type:
[text anzahlKataloge data:brochures]
Any help is much appreciated.
Best Regards,
