I read this: http://wordpress.stackexchange.com/questions/39212/display-posts-of-custom-type-in-hierarchical-order But didn't understand if and how to use the answer.

This what i would like to achieve:

if_user_logged_in

show user's created cpost in hierarchical order


 Is it possible to list custom posts in Homepage with this structure?

No problems in backend:

![No problems in backend][2]

Customer 1 (parent) the_title() - the_permalink() - edit_post_link()

 - Item 1 belongs to Customer 1 Children of Customer 1 the_title() - the_permalink() - edit_post_link()
 - Item 2 belongs to Customer 1 Children of Customer 1 the_title() - the_permalink() - edit_post_link()
 - Item 3 belongs to Customer 1 Children of Customer 1 the_title() - the_permalink() - edit_post_link()
 - Item 4 belongs to Customer 1 Children of Customer 1 the_title() - the_permalink() - edit_post_link()

Customer 2

 - Item 1 belongs to Customer 2 Children of Customer 2 the_title() - the_permalink() - edit_post_link()
 - Item 2 belongs to Customer 2 Children of Customer 2 the_title() - the_permalink() - edit_post_link()
 - Item 3 belongs to Customer 2 Children of Customer 2 the_title() - the_permalink() - edit_post_link()
 - Item 4 belongs to Customer 2 Children of Customer 2 the_title() - the_permalink() - edit_post_link()


And so on, I think you have the point :)

This is how I registered my cPost:

    /*Custom post clienti */
    add_action( 'init', 'register_cpt_cliente' );
    
    function register_cpt_cliente() {
    
        $labels = array( 
            'name' => _x( 'Clienti', 'cliente' ),
            'singular_name' => _x( 'Cliente', 'cliente' ),
            'add_new' => _x( 'Aggiungi nuovo', 'cliente' ),
            'add_new_item' => _x( 'Aggiungi un nuovo cliente', 'cliente' ),
            'edit_item' => _x( 'Modifica cliente', 'cliente' ),
            'new_item' => _x( 'Nuovo client', 'cliente' ),
            'view_item' => _x( 'Guarda cliente', 'cliente' ),
            'search_items' => _x( 'Cerca cliente', 'cliente' ),
            'not_found' => _x( 'Nessun cliente trovato', 'cliente' ),
            'not_found_in_trash' => _x( 'Nessun cliente eliminato', 'cliente' ),
            'parent_item_colon' => _x( 'Cliente superiore:', 'cliente' ),
            'menu_name' => _x( 'Clienti', 'cliente' ),
        );
    
        $args = array( 
            'labels' => $labels,
            'hierarchical' => true,
            'description' => 'Un archivio per gestirli tutti (Cit.)',
            'supports' => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'trackbacks', 'custom-fields', 'comments', 'revisions', 'page-attributes' ),
            'taxonomies' => array( 'category', 'post_tag', 'page-category', 'abruzzo', 'basilicata', 'calabria', 'campania', 'emilia-romagna', 'friulli-venezia-giulia', 'lazio', 'liguria', 'lombardia', 'marche', 'molise', 'piemonte', 'puglia', 'san_marino', 'sardegna', 'sicilia', 'toscana', 'trentino-alto_adige', 'umbria', "valle_d'aosta", 'veneto' ),
            'public' => true,
            'show_ui' => true,
            'show_in_menu' => true,
            'menu_position' => 5,
            'menu_icon' => get_template_directory_uri().'/images/cli20.png',
            'show_in_nav_menus' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'has_archive' => true,
            'query_var' => true,
            'can_export' => true,
            'rewrite' => true,
            'capability_type' => 'post'
        );
    
        register_post_type( 'cliente', $args );
    }


This is my loop that, obviusly works but has no hierarchical structure:

    <?php if ( is_user_logged_in() ) {;?>
        <div id="listaclienti-container">
            <?php global $current_user;
                get_currentuserinfo();
                $idutente = $current_user->ID;
                $loop = new WP_Query( array( 
                   'post_type' => 'cliente',
                   'posts_per_page' => -1,
                   'author' => $idutente) 
                );?>
            
            <ul id="listaclienti">
            	
            	<?php if (have_posts()) { ?>
            	<?php while ( $loop->have_posts() ) : $loop->the_post();?>
            			<li>
            				<h3>
            					<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
            						<?php the_title(); ?><?php edit_post_link('Edit', ' | ', ''); ?>
            					</a>
            				</h3>
            			</li>
            		<?php endwhile;
            	}else{echo 'No posts here';};?>
            </ul><!-- listaclienti -->
        
        </div><!-- listaclienti Container -->
    <?php };?><!-- end of if user_logged_in -->
