Here we will implement a range of features and values. I am using the country of origin example; you can choose what is appropriate to your product range.
Click on Catalog | Features.
Now click on Add new feature and type the name of your first feature and then click on Save.
Next click on the Add new feature value button and type the name of the first value of this feature. Select from the drop-down list the new feature, and then click on Save.
Repeat step 3 for all values of that feature.
Repeat steps 2 and 3 for all of the features you want to create.
Now click on the Catalog tab again and browse to the category of the first product you want to add a feature to. Click on the product to edit it.
Now click on Features.
Select the feature and then the value from the drop-down list and click on Save.
Go and look at the cool Data sheet tab that has appeared with that product on the shop front.
Assign as many products and values as you need.
