Good day!
Is it possible to determine in the header that you are on the detailed page of the catalog?

Answer 1

In general, we got such a "crutch":

public static function isSectionInCatalog($iblockID, $url) {
    $code = array_pop(array_filter(explode( '/',  $url)));
    $arFilter = array("IBLOCK_ID"=>$iblockID, "CODE" => $code);
    $rsSections = CIBlockSection::GetList(array(),array('IBLOCK_ID' => $iblockID, '=CODE' => $code));
    return ($rsSections->Fetch() !== false);
  }

Answer 2

in component_epilog write the desired checkbox to the global variable or page property

Answer 3

$APPLICATION->GetCurPage(false)
