How to display only certain elements in bitrix:catalog?

Question

1C-Bitrix

Which parameter specifies the items to be displayed in the catalog?
Tried like this but doesn't work

$arrFilter = Array( 
"SECTION_ID" => 1,
);

$APPLICATION->IncludeComponent(
  "bitrix:catalog",
  ".default",
  Array(
    "IBLOCK_TYPE" => "catalog",

Answer 1

"FILTER_NAME" => "arrFilter",
UPD. Did NOT notice this parameter specified.
The problem is that the catalog.section component does not accept the global filter [And does not work with it in the code]. Yes, such a problem.
Option 2:
1. Use catalog.top for output (Which this filter takes into account)
2. Finish catalog.section. Move to your space and on line 466

$arFilter = array(
    "IBLOCK_ID"=>$arParams["IBLOCK_ID"],
    "IBLOCK_ACTIVE"=>"Y",
    "ACTIVE"=>"Y",
    "GLOBAL_ACTIVE"=>"Y",
  );

replace with about

if(strlen($arParams["FILTER_NAME"])<=0 || !preg_match("/^[A-Za-z_][A-Za-z01-9_]*$/", $arParams["FILTER_NAME"]))
{
  $arrFilter = array();
}
else
{
  $arrFilter = $GLOBALS[$arParams["FILTER_NAME"]];
  if(!is_array($arrFilter))
    $arrFilter = array();
}
$arFilter = array_merge(array(
    "IBLOCK_ID"=>$arParams["IBLOCK_ID"],
    "IBLOCK_ACTIVE"=>"Y",
    "ACTIVE"=>"Y",
    "GLOBAL_ACTIVE"=>"Y",
  ),$arrFilter);

Of course, at the same time, add the filter name to $arParams in the section.php file in the component template, i.e.
"FILTER_NAME" => $arParams['FILTER_NAME'],

Answer 2

You can filter by different parameters: sections, tags, etc.
By default, if I'm not mistaken, all active elements of the infoblock are displayed.

Answer 3

See the global filter, here is an example dev.1c-bitrix.ru/support/forum/forum6/topic56973
