I’m sorry… Should I show you like this?
<ul id="listPage">
<?php foreach ($list = $page->children()->paginate(10) as $item): ?>
<li>
<span class="number"></span>
<span class="listsubject"><?= $item->urltexts() ?></span>
<span class="downloadpdf"><a href="<?= $item->pdffiles() ?>" target="_blank" download>Download PDF</a></span>
</li>
<?php endforeach ?>
</ul>
