This product demonstrates an ability of the Products Properties Extension multidimensional plugin Pro to use unlimited number of attributes. These attributes are not added as product combinations but as multidimensional plugin Pro dimensions. Each dimension (or attribute) has its own constant impact on a product price.
The Smart Price plugin takes care to calculate the price based on the attribute price impact.
This product also demonstrates free text field and tooltips supported by the Products Properties Extension multidimensional plugin Pro.
