Categories and unlimited subcategories
From AffiliateBang Wiki
After you've created your categories, they can be parented/childed however you want. Your categories sort alphabetically by default, although you can also choose to re-sort them according to your preference.
A popular feature of Bang is the option to make sub-subcategories, sub-sub-subcategories and so on; the only limit being how your theme will display them. Bang has support for unlimited subcategories. You can build your categories or subcategories by item name, keywords, or ASINs.
