В итоге сработал вот этот код фильтра + указать в параметрах catalog.section после фильтра
"BY_LINK"=> "Y",
"SHOW_ALL_WO_SECTION" => "Y",
"SECTION_ID" => '0',
<?
$arFilter = array(
"IBLOCK_ID" => $arParams["IBLOCK_ID"],
"ACTIVE" => "Y",
"GLOBAL_ACTIVE" => "Y",
);
if (0 < intval($arResult["VARIABLES"]["SECTION_ID"])) {
$arFilter["ID"] = $arResult["VARIABLES"]["SECTION_ID"];
}
elseif ('' != $arResult["VARIABLES"]["SECTION_CODE"]) {
$arFilter["=CODE"] = $arResult["VARIABLES"]["SECTION_CODE"];
}
$obCache = new CPHPCache();
if ($obCache->InitCache(36000, serialize($arFilter), "/iblock/catalog")) {
$arCurSection = $obCache->GetVars();
} elseif ($obCache->StartDataCache()) {
$arCurSection = array();
if (Loader::includeModule("iblock")) {
$dbRes = CIBlockSection::GetList(array(), $arFilter, false, array("ID"));
if(defined("BX_COMP_MANAGED_CACHE")) {
global $CACHE_MANAGER;
$CACHE_MANAGER->StartTagCache("/iblock/catalog");
if ($arCurSection = $dbRes->Fetch()) {
$CACHE_MANAGER->RegisterTag("iblock_id_".$arParams["IBLOCK_ID"]);
}
$CACHE_MANAGER->EndTagCache();
} else {
if(!$arCurSection = $dbRes->Fetch()) {
$arCurSection = array();
}
}
}
$obCache->EndDataCache($arCurSection);
}
if (!isset($arCurSection)) {
$arCurSection = array();
}
$APPLICATION->IncludeComponent(
"bitrix:catalog.smart.filter",
".default",
array(

Простой
