In Shopit, you can allocate a product to a Primary and a Secondary category.
What is a Primary Category?
A Primary category is where a product 'lives' and is reflected in where you go to edit that product. For example, a kids shoe would live in the Shoes category of a website, alongside other shoes for men and women.
What is a Secondary Category?
A Secondary category is where a product is advertised or linked to. For example, a kids shoe may be advertised in a new category that groups all kid products together, or a flash sale category that groups all 'Back to School' items together.
