Item Subcategories

You can set up subcategories for items by going to Admin -> Inventory -> Search Categories.

You can assign these search categories to items when editing the items. Look for the Search Category section under B2B. 

Items can be assigned to more than one category.

You can search for items using search categories by clicking the magnifying glass icon next to item search boxes (ex. item search boxes for quotes, fulfillment orders, and POS).
