Related products are showing with out of stock products, I want to hide out of stock products from related products only.

$this->_itemCollection = $product->getRelatedProductCollection()

I have found above code to get related product collection. How can I filter this collection by is_salable?


Have you tried something like this? https://magento.stackexchange.com/a/130070/3566

Not sure if this could be achieved with a plugin approach, setting a aroundGetItems plugin, after would not be an option, as collection is loaded in _prepareData() method

 * @return $this
protected function _prepareData()
    $product = $this->_coreRegistry->registry('product');
    /* @var $product \Magento\Catalog\Model\Product */

    $this->_itemCollection = $product->getRelatedProductCollection()->addAttributeToSelect(

    if ($this->moduleManager->isEnabled('Magento_Checkout')) {


    foreach ($this->_itemCollection as $product) {

    return $this;

So, I'd rewrite Magento\Catalog\Block\Product\ProductList\Related & use addInStockFilterToCollection(), as explained in the quoted answer
