How to create a Size field on Commerce product content fields? I am new to Drupal Commerce and I have set up a store. But the problem is that adding variations for each product is a pain, especially when the product has more than 5 colors and 4 sizes. 

What I want to do is to have a size Field in Content type instead of product type's fields so that I add the sizes only once (like choosing the categories or collection).

And then customers can select a radio button or so to be able to add the item to the Shopping Cart.

How can I make it work or is there another solution for it?
I'd go for another solution/approach, as detailed below ...

Commerce Bulk Product Creation

You may want to use the Commerce Bulk Product Creation module. Excerpt from its project page:


  ... facilitates the creation of groups of related products in bulk. Product administrators can select a number of options for various fields, and a product will be created for all possible combinations of these values. Out of the box, only list fields are supported for this, but an API exists to enable other types of fields for 'combination creation'.


Attention: this module doesn't have an official release yet (only an RC6), though with over 1.200 reported installs, it seems it is pretty stable / trustworthy.

Commerce Backoffice

Another option is to use the Commerce Backoffice module, e.g. because of the auto creation of product display nodes. It provides the backoffice functionality present in Commerce Kickstart (V2), and contains these sub-modules:


Commerce Backoffice Product (commerce_backoffice_product).
Commerce Backoffice Order (commerce_backoffice_order).
Commerce Backoffice Content (commerce_backoffice_content).


This module (and a few dependencies) provides the rich store owner experience that has made Commerce Kickstart 2 so popular (and prevents that you have to install the entire Commerce Kickstart distribution). And there is a great video introduction about it also.

Note: if you use Commerce Backoffice, you most probably also want to use the Shiny administration theme, also used in Commerce Kickstart (V2).
