# Categories > A flat catalogue filter like “Ebooks” or “New”, with its own URL and a place in the menu. Page: https://sellstamp.com/docs/products/categories ## Creating and using categories Create them under **Products → Categories**: a name and a URL slug. Put a product in one or more categories from the product form. Categories are flat, with no parent and child levels, and they change nothing about price or visibility. Deleting a category removes it from its products and changes nothing else.
