Extra field on Shipping Data

Hi,

With the Starter edition, you will be limited to only custom address fields. However, with the Business edition, you will be able to add custom order fields which will be linked to the order and displayed on the checkout. You will also be able to add custom item fields which will be displayed on the product page and attach to each product in the cart (and then in the order).

It's possible to hide your custom address fields on some forms and not on others with a line of CSS. But the field needs to not be required is that case, otherwise, the system will refuse the form. If you give us the URL of your shop, we should be able to give your more precise directions concerning the CSS to use to hide your custom address field.

I'm not an expert in Spanish but I should be able to handle it.

On our demo website you can hide the post code field with this:
#address_post_code{ display:none; }

In HikaShop, you have addresses attached to the user. Then, during the checkout, the user can use that address as a billing address and/or as a shipping address. So, the edition popup is the same for both and if you change something for an address used as billing, it will also be changed if it's used as shipping.
I think that the solution will be to use custom order fields. That way the fields will be displayed on the checkout directly and you will only have them once per order.

Only with the Business version.
