products multiple categories more than one category
Question:
How do I put products in multiple categories?
Response:
You can put a product into multiple categories by editing the product. Once you are in edit mode on a product, scroll down to the product options section, add the number of additional categories in the additional categories field, and click next. Toward the bottom of page two you can define those categories using the pulldowns.
If you are wanting to modify many products at once, you can also do this with spreadsheets by going to Products / Import / Product Category Import.
