Divide portfolio with taxonomies (compatible?)

Please help!!

I may have explained it unclear. I basically need to duplicate “Portfolio items” in the wp menu a few times. Either I can create custom post types and add the necessary code(s) to make them work and look like the portfolio, or I duplicate the necessary portfolio files/codes and rename them into “Customers”, “Partners” and “Products”.

Important is that I also have to advanced layout builder.

This is extremely important in my case, so please give me your feedback.

An example of what I have already added as PHP, currently still as regular post types:

// Add new post type for Customers

add_action ('init',  'customers_init');

function customers_init()

{

$customer_labels = array(

'name' => _x('Customers', 'post type general name'),

'singular_name' => _x('Customer', 'post type singular name'),

'all_items' => __('All customers'),

'add_new' => _x('Add customer', 'customers'),

'add_new_item' => __('Add Customer'),

'edit_item' => __('Edit Customer'),

'new_item' => __('New Customer'),

'view_item' => __('View Customer'),

'search_items' => __('Search Customer'),

'not_found' =>  __('No customers found'),

'not_found_in_trash' => __('No customers found in Trash'),

'parent_item_colon' => ''

);



$args = array(

'labels' => $customer_labels,

'public' => true,

'publicly_queryable' => true,

'show_ui' => true,

'query_var' => true,

'rewrite' => true,

'capability_type' => 'post',

'hierarchical' => false,

'menu_position' => 5,

'supports' => array('title','thumbnail','editor'),

'has_archive' => 'customers'

);

register_post_type('customers',$args);

}



// Add custom taxonomies

add_action( 'init', 'create_taxonomies', 0);



function create_taxonomies()

{

// Customer type

$country_labels = array(

'name' => _x('Countries', 'taxonomy general name'),

'singular_name' => _x('Country', 'taxonomy singular name'),

'search_items' => __('Search countries'),

'all_items' => _x('All countries'),

'most_used_items' => null,

'parent_item' => null,

'parent_item_colon' => null,

'edit_item' => __('Edit Country'),

'update_items' => __('Update Country'),

'add_new_item' =>  __('Add country'),

'new_item_name' => __('New Country'),

'menu_name' => __('Countries')

);

register_taxonomy('customer-country', 'customers', array(

'hierarchical' => true,

'labels' => $country_labels,

'show_ui' => true,

'query_var' => true,

'rewrite' => array('slug' => 'customer-country' )

));

}
