A custom category is any word or phrase you'd like to use to categorize your resources. You can create a custom category in addition to our standard category options. Once you create a custom category, you can assign products to that category in addition to the standard options.
To create a custom category, go to your Product Listings page and click on the "Manage Your Categories" link.
Once you've added custom categories, the "Custom Category" field in your product listings will be populated with these options.
If you'd like, you can select multiple custom categories for a product:
On a PC, hold the Control button as you click to select or de-select multiple categories.
On a Mac, hold the Command key (⌘) and click to select or de-select multiple categories.
