Change the conditions for sorting goods in Bitrix?

Question

1C-Bitrix

Good afternoon!
Tell me, who knows how to set up sorting by price in such a way that products without a price (the price is not indicated) are always displayed at the end of the list, regardless of whether the site user has enabled sorting by price in ascending or descending order?

Answer 1

<? //Если цена в виде параметра
$arParams['ELEMENT_SORT_FIELD']="PROPERTY_PRICE";
$arParams['ELEMENT_SORT_ORDER']="desc";
?>
<? // Если встроенный функционал цен
$arParams['ELEMENT_SORT_FIELD']="catalog_PRICE_1";
$arParams['ELEMENT_SORT_ORDER']="desc";
?>
<?$intSectionID = $APPLICATION->IncludeComponent(
  "bitrix:catalog.section",
  "",
  array(
    "IBLOCK_TYPE" => $arParams["IBLOCK_TYPE"],
    "IBLOCK_ID" => $arParams["IBLOCK_ID"],
    "ELEMENT_SORT_FIELD" => $arParams["ELEMENT_SORT_FIELD"],
    "ELEMENT_SORT_ORDER" => $arParams["ELEMENT_SORT_ORDER"],
    
    "ELEMENT_SORT_FIELD2" => $arParams["ELEMENT_SORT_FIELD2"],
    "ELEMENT_SORT_ORDER2" => $arParams["ELEMENT_SORT_ORDER2"],
