O Magento 2 não tem um URL de mapa do site html para categoria e produtos, como no magento 1.xx. Para isso, você pode criar uma página do CMS como 'sitemap /' e chamar um arquivo phtml
que incluirá o código personalizado para chamar todas as categorias
Na página cms, chame isso:
{{block class="Magento\Framework\View\Element\Template" template="Magento_Theme::sitemap.phtml" name="customsitemap"}}
então, em phtml, chame isso:
<?php
$objectManagerr = \Magento\Framework\App\ObjectManager::getInstance();
$categoryFactory = $objectManagerr->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
$categoryy = $categoryFactory->create()
->addAttributeToSelect('*');
//->addAttributeToFilter('is_active',1)
//->addAttributeToFilter('is_anchor',1);
$excludedCategory = array(0);
?>
<ul class="sitelist">
<?php foreach ($categoryy as $cc): ?>
<?php if(!in_array($cc->getId(), $excludedCategory)):?>
<div class = "sitemap-list" style="float:left;">
<?php if ($cc->getLevel()==2):?>
<li>
<h3><a href="<?php echo $cc->getUrl(); ?>"><?php echo $cc->getName(); ?></a></h3>
<?php
if($cc->getChildren())
{
$sub = explode(",", $cc->getChildren());
$categoryFactorysub = $objectManagerr->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
$categoryysub = $categoryFactorysub->create()
->addAttributeToSelect('*');
$subcat=$categoryysub->addFieldToFilter('entity_id', array('in' =>$sub));
//$subcat->printlogquery(true);exit;
?>
<ul style="margin-left:15px;">
<?php foreach ($subcat as $subcategories){ ?>
<?php if ($subcategories->getLevel()==3):?>
<div class = "sitemap-list">
<li>
<?php if($subcategories->getImageUrl()): ?>
<div class="mega-menu-ad">
<img src="<?php echo ($subcategories->getImageUrl()); ?>" width="25" height="25" />
</div>
<?php endif; ?>
<a href="<?php echo $subcategories->getUrl(); ?>"><?php echo $subcategories->getName(); ?></a>
<?php
if($subcategories->getChildren())
{
$subSubCat = explode(",", $subcategories->getChildren());
$subsubCatFactory = $objectManagerr->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
$subSubCatCollection = $subsubCatFactory->create()
->addAttributeToSelect('*');
$subSubCollection=$subSubCatCollection->addFieldToFilter('entity_id', array('in' =>$subSubCat));
?>
<ul style="margin-left:20px;">
<?php foreach ($subSubCollection as $subSubcategories){ ?>
<div class = "sitemap-list">
<li>
<?php if($subSubcategories->getImageUrl()): ?>
<div class="mega-menu-ad">
<img src="<?php echo ($subSubcategories->getImageUrl()); ?>" width="25" height="25" />
</div>
<?php endif; ?>
<a href="<?php echo $subSubcategories->getUrl(); ?>"><?php echo $subSubcategories->getName()?></a>
</li>
</div>
<?php } ?>
</ul>
<?php } ?>
</li>
</div>
<?php endif;?>
<?php } ?>
</ul>
<?php } ?>
</li>
<?php endif;?>
</div>
<?php endif;?>
<?php endforeach; ?>
</ul>
Dessa forma, você pode criar facilmente um URL de mapa do site no Magento 2.
