Change Header position

[bestcons]

Our Historical Society website presents large amounts of Photo's as Articles (amongst others). We have made a top-category Photo's, sub-categories such as Schools and sub-sub categories for named schools such as Medlerschool (See attachments of screen images).
Unfortunately the lay-out of the various categories differ and we have not been able in the VM Configuration to position the (sub)-category names as Headers on top and the Navigation as trailers.
We use Joomla 3.9.25 and VM 3.8.8.
Please advice.

Yes, you can but not in admin -  in PHP file for category layout - move manually.

I am able to change in php, but only if someone else is so kind to describe the recipe.

You can see this in red on the 3 attachments. Thank you, don't hesitate if you need more information.

if your template is reasonably std. then the header is

<?php if (!empty($this->category->category_name)) { ?>
<h1><?php echo vmText::_($this->category->category_name); ?></h1>
<?php } ?>

so move the

// Show child categories
if ($this->showcategory and empty($this->keyword)) {
   if (!empty($this->category->haschildren)) {
      echo ShopFunctionsF::renderVmSubLayout('categories',array('categories'=>$this->category->children, 'categories_per_row'=>$this->categories_per_row));
   }
}

below that

same for the clearly commented search block

templates\YOURTEMPLATE\html\com_virtuemart\category\default.php

Unfortunately
<?php if (!empty($this->category->category_name)) { ?>
<h1><?php echo vmText::_($this->category->category_name); ?></h1>
<?php } ?>
was not found in the default.php of the template. The file is attached.
