This is my loop:
<div class="band"><Loop type=page parent=31416 include_children=true order=asc orderby=title>
<div class="item"><a href="{Field url}" class="card"><If field image exists><div class="thumb" style="background-image: url({Field image_url});"></div></If>
<article>
<h4><Field title /></h4>
<p><Field excerpt auto=true /></p>
</article></a></div>
</Loop>
</div>
I’d like to generalize this to a template that can pick up the ID from the current page and use it with the parent operator. Is there a variable for that?
