Question

1C-Bitrix

There is an infoblock, it has elements that are at the first nesting level and at the second (in documents),
you need to display elements through the news.list component that are only at the first level (elements that do not need to be displayed in documents).

Answer 1

Look towards filtering by SECTION_ID

Variant example, but not tested

<? $GLOBALS['arrFilter'] = array('!=SECTION_ID' => false);?>
