Как модифицировать indexnews.tpl чтобы выводило по три новости за такт! Вот пример PHP кода:

$data = array(
    array('title' => "TITLE1", 'link' => "LINK1"),
    array('title' => "TITLE2", 'link' => "LINK2"),
    array('title' => "TITLE3", 'link' => "LINK3"),
    array('title' => "TITLE4", 'link' => "LINK4"),
    array('title' => "TITLE5", 'link' => "LINK5"),
    array('title' => "TITLE6", 'link' => "LINK6"),
    array('title' => "TITLE7", 'link' => "LINK7"),
    array('title' => "TITLE8", 'link' => "LINK8"),
    array('title' => "TITLE9", 'link' => "LINK9"),
    array('title' => "TITLE10", 'link' => "LINK10"),
); 

$rowCounter = 1;
$dataCounter = 0;
$newRow = true;

while($dataCounter < count($data))
{
    if($newRow == true)
    {
        echo '<div class="row mb-3 text-center">'."\n";
        $newRow = false;
    }

    echo "\t".'<div class="col-4 themed-grid-col"><a href="'.$data[$dataCounter]['link'].'">'.$data[$dataCounter]['title'].'</a></div>'."\n";

    if(($rowCounter / 3) == 1 OR ($rowCounter % 3) == 0 OR (count($data) - $dataCounter) < 3)
    {
        echo '</div>'."\n";
        $newRow = true;
    }
    $rowCounter++;
    $dataCounter++;
}
