Using Drupal Commerce you can set fields in the product entity which can function as attribute selection fields. The visitor can use them to switch the variations of a product.
I created a field called SIZE which allows the visitor to switch the variations of a product. This works fine. Now I need to allow to change the variation by clicking in a image of the variation. See my capture to get the idea.
I create an image field and set it to 1 value, but the “Attribute field settings” area didn’t show up. In this area you can check “Enable this field to function as an attribute field on Add to Cart forms.”
I thought this module could help, but as far as I see it is not useful for this: https://www.drupal.org/project/commerce_fancy_attributes
