Parent-child Product Features

[jawaid]

I am trying to modify product features in a way that I can define one product feature as parent of another product feature.

 

For example, I add two product features Feature1 and Feature2. In Feature1 I add values like F1value1, F1value2, and so on. Similarly, when defining values for second feature I want to map a parent of that value. Like if I define value of Feature2 to be F2V2 I also want to tell that its parent is F1Value1.

 

So, a feature value can have one parent and multiple feature values can have same parent. This is a one-to-many relationship between parent and child feature.

 

To do this what I think I need to modify product_features table and add a parent_id column. But how can I update the Product Feature screen to reflect the changes in DB?

 

Any help would be appreciated.
