There is a way to achieve this :
Create a bundled product named "Auto Floor Mats Set".
Create 4 configurable products named :
- "Front-Left Mat"
- "Front-Right Mat"
- "Back-Left Mat"
- "Back-Right Mat"
then
Create 3 simple products for each configurable product and associate them with configurable products created in previous step ( e.g. create simple products named :
- "Red Front-Left Mat"
- "Green Front-Left Mat"
- "Blue Front-Left Mat"
and associate them with configurable product "Front-Left Mat")
In your bundled product, go to "Bundle items" -> "Add New Option" and create 4 options :
- "Front-Left"
- "Front-Right"
- "Back-Left"
- "Back-Right"
and add 3 selections for each option. e.g. add simple products :
- "Red Front-Left Mat"
- "Green Front-Left Mat"
- "Blue Front-Left Mat"
as selections for option "Front-Left Mat".
That's all !
