I'm making a shoe store. Different shoe types have different conversions between sizes - Running shoe size US 8 is 26 cm and Wrestling shoe size US 8 is 25 cm. I'm using two attributes for each shoe type - one with option "US ..." and one with "US ... / ... cm".
The idea is to use the first attribute to filter the results in the layered navigation so it looks like
- US 8
- US 9
- US 10
and not like
- US 8 / 26 cm
- US 8 / 25 cm
- US 9 / 26.5 cm
- US 9 / 25.5 cm
- US 10 / 27 cm
- US 10 / 26 cm
I need to use the second attribute on the Product page so the user can select the right size.
The problem is that both attributes are required to add the product to the cart.
How can be done only the second attribute to be required and the first attribute be used only for filtering? Am I on the right way?
