Features
This is very useful. Suppose you have a range of products and they all have features in common. Take for instance teddy bears. They are all made of something. But what about if within your range, what they were made of varied, and you wanted a simple way of making the information available without polluting the product description? An example would be useful.
I have a range of teddy bears and they are made from super-soft cotton, micro-fiber, or wool knit. I can create a feature and call it 'Material'. I can then create a range of 'Values' for 'Material'. Super-soft cotton, micro-fiber, and wool knit. And I can assign values to any products that I choose.
You can create as many features and associated values as you need. You might want a country of origin feature, with assigned values of 'Europe', 'China', and 'India'. You might have products with a manufacturer's rating. Take Intel processors for example. They all have a star rating from 1 to 5. You could create a feature of colors...
