Many merchants will need to set up sub-categories, and some may need more than one level of sub-categories. This is simple to accomplish in the Nexternal platform.
The Nexternal Order Management System (OMS) supports an unlimited category hierarchy (categories, subcategories, sub-subcategories, etc.)
When creating a Primary (top-level) category, simply leave the pulldown called "subcategory of" at "none".
To create a subcategory of a top-level category, simply use the pull-down called "subcategory of" to pull down to the primary category under which you want this subcategory to appear.
Please be aware that a subcategory can not contain products and also be eligible to have sub-subcategories assigned to it. Put more broadly, a category (whether top level or a subcategory) can have either products or subcategories in it, but not both. If you find that a category already has products and you need to create a subcategory, you may relocate those products to other categories, therefore emptying the category, which will allow you to then add the subcategories or sub-subcategories beneath it. If the products that were in the top-level category will belong in the subcategories you are creating, you may wish to create a temporary hold category (with internal visibility), into which to place these products until after you create the subcategories, and then relocate those products again into the appropriate subcategories.
Moving products around can be done manually or with spreadsheets, but note that the spreadsheet process is very sensitive and should only be employed by users with a solid understanding of spreadsheets and who are extremely detail-oriented, so as to avoid unintended consequences. Before using spreadsheets in this circumstance, we recommend doing a complete backup of the entire product database and saving it on your hard drive, just in case.
