On the product detail page, I've related products I wish to display a short description of the product on my related product on the product detail page in magento 2.
Please help!
$_item->getData('short_description');
Hello @mamunbpaul2dca
Check which file is called for the related product list after enabling the frontend template suggestions path.
If indeed the file is from your theme, change it; if the file is from Magento's default items.phtml, replace it with your theme's version.
Only Magento Open Source users can add product descriptions in the editor.
