How to create a product without a variation? I'm migrating to drupal commerce (kickstart 2) from woocommerce and contao isotope.

My biggest problem was/is understanding the terminology behind it - product types, variations, etc.

In woocommerce and isotope the product categories would be for example:
- Books
- Computers
- T-Shirts.

Each category would then have individual products in it, and each product would have optional variation.

I'm having hard time understanding this in kickstart2. More than that, is it even possible to create a product without variations? How can I create a store of simple unique products that would belong to different categories (woocommerce terminology), without variables.

For example:


Books: product1, product2, product 3, ... (no variables)
PCs: -- || --
...


Thanks.
It is - as You said - difference of terminology.
The easiest way for You would be trying this: https://simplytest.me/
Here You can quickly test Drupal modules and whole distributions. Please try Commerce Kickstart with this tool and during install click to install demo content.

There You'll see that Variations are more like Categories in Your meaning:
Each product display must have one or more product variations, which is why each product display type has a matching product variation type.
Different product variation types have different fields, used for storing images, attributes such as color and size, as well as any other information.

And Categories are more like taxonomy - You can list colors, sizes etc there and reuse it in multiple products.

Hope i helped You a little :)
