First of all, I'm new, so sorry, because maybe I'm writing this in one place not for this.

Question is, it's not possible to filter only products that have user selected attribute with stock? Because block show products with attribute stock = 0

I tried this chages, but don't work at all

foreach ($sub_queries as $sub_query)
					{
						  $query_filters_where .= ' AND p.id_product IN (SELECT pa.`id_product`
						FROM `'._DB_PREFIX_.'product_attribute_combination` pac
						LEFT JOIN `'._DB_PREFIX_.'product_attribute` pa
						ON (pa.`id_product_attribute` = pac.`id_product_attribute`)
						LEFT JOIN `'._DB_PREFIX_.'stock_available` sa
ON (sa.`id_product_attribute` = pac.`id_product_attribute` AND sa.`quantity` > 0)'.
						Shop::addSqlAssociation('product_attribute', 'pa').'
						WHERE '.implode(' OR ', $sub_query).') ';
					}	


public function indexAttribute($id_product = null)
	{
		if (is_null($id_product))
			Db::getInstance()->execute('TRUNCATE '._DB_PREFIX_.'layered_product_attribute');
		else
			Db::getInstance()->execute('
				DELETE FROM '._DB_PREFIX_.'layered_product_attribute 
				WHERE id_product = '.(int)$id_product
			);
		
		Db::getInstance()->execute('
			INSERT INTO `'._DB_PREFIX_.'layered_product_attribute` (`id_attribute`, `id_product`, `id_attribute_group`, `id_shop`)
			SELECT pac.id_attribute, pa.id_product, ag.id_attribute_group, product_attribute_shop.`id_shop`
			FROM '._DB_PREFIX_.'product_attribute pa'.
			Shop::addSqlAssociation('product_attribute', 'pa').'
			INNER JOIN '._DB_PREFIX_.'product_attribute_combination pac ON pac.id_product_attribute = pa.id_product_attribute 
			INNER JOIN '._DB_PREFIX_.'stock_available sa ON (sa.id_product_attribute = pac.id_product_attribute AND sa.quantity > 0)
			INNER JOIN '._DB_PREFIX_.'attribute a ON (a.id_attribute = pac.id_attribute) 
			INNER JOIN '._DB_PREFIX_.'attribute_group ag ON ag.id_attribute_group = a.id_attribute_group
			'.(is_null($id_product) ? '' : 'AND pa.id_product = '.(int)$id_product).'
			GROUP BY a.id_attribute, pa.id_product , product_attribute_shop.`id_shop`'
		);
		
		return 1;
