I have created a theme with a custom post type called 'project' and there is a problem. I want to show 5 different custom post type categories on a page in different portions, like posts to show on pages from their respective categories. Is there any solution?

this is my custom post type code with custom texonomy

<?php

{
    register_post_type(
        'Project',
        array(
            'labels'               => array(
                'name'                => __('Project', 'text_domain'),

Here is my code to display one category

$args = array(
'post_type' => 'project',
'posts_per_page' => 200, 
'cat' => 'Initiatieffase'
    );
$loop = new WP_Query($args); while ($loop->have_posts()) : $loop->the_post();
echo '<li><a href="' . the_permalink() . '">' . the_post_thumbnail() . '</a></li>';
endwhile;
wp_reset_query();
