In my Joomla shop (J2STORE), under a product, I have a quantity dropdown that let the price be dynamic on the product page. However, I have made the dropdown display a placeholder first, before you select a quantity. The problem is then that the price is still showing - so I need to write some sort of code in the PHP-file, that tells something like "if no quantity is selected, echo this "---" or "if the placeholder is selected, echo this "---" I still need the quantity dropdown to work afterwards, so I can not just replace the price part. Can someone help me out, what I can do here?
I have tried talking with the developers, but they do not have time to help me out with this customization.
