Answer 1

You can do this without ajax

$this->load->model('catalog/product');
$this->load->model('catalog/category');

/* 0 = Выбрать все родительские категории */
$categories = $this->model_catalog_category->getCategories( 0 );

foreach ($categories as $category) {
    $filter = [
        'filter_category_id' => $category['category_id'],
        'filter_sub_category' => true, //Включать в выборку товары из дочерних категорий
        'start' => 1,
        'limit' => 4 //Количество товаров
    ];
    $products = $this->model_catalog_product->getProducts($filter);

    $data['category_tabs'][] = [
        'category_id' => $category['category_id'],
        'name'        => $category['name'],
        'products'    => $products
    ];
}
