            if ($this->getShowRootCategory()) {
                $this->setCategoryId($this->_storeManager->getStore()->getRootCategoryId());
            }

            // if this is a product view page
            if ($this->_coreRegistry->registry('product')) {
                // get collection of categories this product is associated with
                $categories = $this->_coreRegistry->registry('product')
                    ->getCategoryCollection()->setPage(1, 1)
                    ->load();
                // if the product is associated with any category
                if ($categories->count()) {
                    // show products from this category
                    $this->setCategoryId(current($categories->getIterator()));
                }
            }
