Display subcategories list on product page

[proconcept]

Hello everyone,

 

I am trying to display a list of subcategories in product.tpl (prestashop 1.7) but the function getProductCategoriesFull returns all categories any ideas on how to filter the depth of subcategories to display ??

 

For my case I want to display only 3rd level categories in that list.

 

Thanks in advance !

 

      <label class="label">{l s='Compatible Printer Models :' d='Shop.Theme.Catalog'} </label>
                <ul class="productcats">
      
                     {foreach from=Product::getProductCategoriesFull(Tools::getValue('id_product')) item=cat name=cats}
                <li class="billakos"><a href="{$link->getCategoryLink({$cat.id_category})}" title="{$cat.name}">{$cat.name}</a></li>
    
                {/foreach}
