Magento 2 parent theme behavior

Question

we have a complex shop structure with an multishop base theme from scratch and about 10 child themes.

The structure is as follows:

• multishop_theme/
  default (main theme content)
  child theme 1 (other css, layout ...)
  child theme 2
  child theme 3,4,5,6,7 and so on
  

Now we want to add other shops that are not based on our multishop_theme but we want to share some defaults (payment templates, customer, checkout), so that we dont repeat ourselves. What is the best structure in this case?

• multishop_theme/
  default
  child
  child
  
• default/default
  
• singleshop_themes/
  theme 1
  theme 2
  

So the multishop_theme/default is based on default/default, and the multishop childs are based on multishop_theme/default.

The new shops are based on default/default too. What do you recommend?

Best regards

Answer 1

I ask myself one question, why you create one theme for each store ? if the purpose is to have a different design, you can create a different css per storeview like this: app/design/frontend/{Vendor}/{themename}/i18n/en_US/css/style.css, app/design/frontend/{Vendor}/{themename}/i18n/fr_FR/css/style.css etc...

How ever if the purpose is to change completely the design, layout, templates, rootcategories per store, in this case I understand why stores, storeviews.

So I thing there no other solution except create different themes-childs exemple :

app/design/frontend/Luma/luma-child1
                     |___luma-child2
                     |___luma-child3

app/design/frontend/Blank/blank-child1
                     |____blank-child2
                     |____blank-child3

Answer 2

You can create new theme inside multishop_theme set parent theme as luma or blank whatever you want to use it.

multishop_theme/

• default
• child
• child
• singleshop_themes (Newly created theme).

Copy and paste modules according to your requirement from your base theme to singleshop theme.

I hop it will help you.
