Post format or Type for List Type Posts

You may simply use register_post_type and register_taxonomy to do so:

function add_cpt_salads(){
    $labels = array(
        'name'                          => __( 'Salads', 'your-text-domain' ),
        'singular_name'                 => __( 'Salad', 'your-text-domain' ),
        'menu_name'                     => __( 'Salads', 'your-text-domain' ),
        'all_items'                     => __( 'All Salads', 'your-text-domain' ),
        'add_new'                       => _x( 'Add new', 'Salads', 'your-text-domain' ),
        'add_new_item'                  => __( 'Add New Salad', 'your-text-domain' ),
        'edit_item'                     => __( 'Edit Salad', 'your-text-domain' ),

    );
    $args = array(

        'labels'                        => $labels,
        'description'                   => __( 'Salad items', 'your-text-domain' ),

                'show_in_menu'          => true,
                    'show_in_admin_bar' => true,
                    'menu_position'     => 5,

        'register_meta_box_cb'          => 'fjn_salads_register_meta_box',
        'taxonomies'                    => array( 'salads_category', 'salads_tag' ),

        'query_var'                     => true,
        'can_export'                    => true,
    );
    register_post_type( 'salads', $args );
    register_taxonomy(
        'salads_category',
        'salads',
        array(
            'label'                     => __( 'Salads category', 'your-text-domain' ),
            'rewrite'                   => array( 'slug' => 'salad_cat' ),
            'hierarchical'              => true
        )
    );
}
add_action( 'init', 'add_cpt_salads', 0 );

UPDATE

You should add the above snippet to your current theme’s functions.php file.

Then you should go to WordPress admin and under Salads menu, add:

  • Best Veg Salads
  • Best Non-Veg Salads
  • Best XYZ Salads

using Add Salad category submenu.

Then add:

  • Salad #1
  • Salad #2
  • Salad #x

using Add New Salad submenu, and choose categories for them.

Now in the root directory of your current theme, create a new file named page-salads.php and put this in it:

$terms = get_terms( 'salads_category' );
foreach( $terms as $term ){
    $posts = new WP_Query( "taxonomy='salads_category'&term=$term->slug&posts_per_page=-1" );
    if( $posts->have_posts() ){?>
        <h2><?php echo $term;?></h2><?php
        while( $posts->have_posts() ){
            $posts->the_post();
            $the_title();
            //Do you general query loop here ...
        }  
    }
}

Then in WordPress admin, go to Pages and add a page, named Salads, and take care of the slug to be as:

http://{your-home-url}/salads

like:

http://localhost/mywebsite/salads

and save. Then go to Settings>Permalinks and hit the Save changes button and in your browser enter the following URL:

http://localhost/mywebsite/salads

That is all.
