How to divide goods into groups?

Question

1C-Bitrix

Hello! What is the best way to divide products into groups? There is a property "Printed Circuit Boards" and its values ​​"Large Boards", "Medium Boards", "Small Boards". By this property it is necessary to divide the list of goods into groups. Now I do this:

foreach ($arResult["ITEMS"] as $cell => $arElement) {
     if ($arElement["PROPERTIES"]["BOARDS"]["VALUE_XML_ID"] == "big_boards")
          continue;
}

In fact, it turns out 3 foreach loops. Is it correct to do the breakdown like this or can it be done differently?

Answer 1

one loop with three ifs is enough
