How to show helper text / hint / label under product attributes in magento2?

Question

I want to show some helping text under custom product attributes in the product grid in adminhtml. Is this possible? Thanks for guidance!

Answer 1

I found it: You have to set the column 'note' in the eav_attribute table. e.g.

UPDATE eav_attribute SET note='Only characters allowed' WHERE attribute_code='my_attribute_code';
