Should I use a button or a text link to trigger a downward slide with content section on ecommerce shop's product page?
Update: The opening content should display next to the product image just above short product description. It would be about part payment options and it is not needed by all customers, but still important.
I would assume that button would be preferred solution as it is kind of an action. Link would suggest other kind of behaviour.
However now I think that accordion might work also. Just the text row and maybe a plus icon.
