I want to know is there any method that a dropdown is shown for the different weight of the product at user side. Here my site is hexkart.com . This is an online fruit and vegetable online store. I want to show the different price for the different weight of the same product.
For example like Potato 1 kg price is 20 and for 500gm price is 11 then. I want to select it from dropdown.
Yes, they are called options - here is the doc link about it.
