'Properties' refers to classifications such as 'free -range', 'organic' and 'local'. In OFN there is the option to assign properties to products and/or producers. If a property is applied to a producer, it automatically applies to all products, but you can change them within the product properties menu. When the customer is browsing the OFN directory and shops they can filter according to these properties.
Each instance can setup their own list of properties. The properties that are available on the Australian instance are shown below as an example
Go to Products on the horizontal blue menu, and then select Properties in the green horizontal menu.
Use the + New Property button to add properties.
