I added the new product sorting attribute related to
price in category page like
price low to high and
price high to low. It showed on
Sort By drop down. It is working fine for configurable product and simple product but the problem is, it is working grouped products case.
Grouped product shows the price of their
lowest simple product price in category page.
For Reference please see the screenshot
For Reference I use code for price sorting
Any help, experience and knowledge sharing would be appreciated.
