Magento 2.3 - have categories with no product show subcategories rather than error
When I visit a category that has no products, it will say We cant find products matching the selection
For categories with no products, I would prefer it show a list of the categories with the category thumbnail image.
I have other minor tweaks to a magento 2.3 webstore that I can use - if this works out, I would like to develop a relationship with a magento 2.3 developer that can also do basic theme customizations.
Thank you!
