Does Simple Detail on Configurable Product for Magento 2 support custom options and custom attributes?
Thanks for your interest in BSSCommerce Simple Details on Configurable Product for Magento 2.
For your question, we'd like to inform you that the extension supports Configurable Products only, child products without custom options (which default Magento does not support)
On the other hand, if the product has custom attributes, the custom attributes will show in the More information tab as the image.
We hope the information is useful for you.
If you have any questions, please let us know.
