How can I create a category with a .no URL instead of .se that is our default?

You can do this by creating the category and adding a translation for the desired language.

Go to Products > Categories and click New to create the category. In the first view, you enter texts for the default language (usually Swedish).

To make the category available on the Norwegian site (.no), go to the Translate tab and add at least the category name in Norwegian. Once a Norwegian name is added, a URL is automatically generated based on that name and will be used for the .no market.

In the example above we refer to a .no URL with Norwegian as language, the process is the same for other domains and languages.
