Add new fields to combinations

[DOKI4ever]

Hello everyone,

 

Does anybody know how can i add new fields to combinations?

 

In the project that i'm developing, the client need to add a custom html flied to each combination to add html content ( in combinations you have the price change, reference field, etc. it would be a new field with html on it).

 

So when the user selects a combination in the product view, it will show the content of the field that we added to the combination to the user ( i will have to modify the product.tpl to add this but the problem is that i don't know how to do the first part).

 

Is there any module that let¡s me do this or some kind of tutorial?

 

Thanks in advance.
