Hello,
Example:
Parent product: SPECIAL! Bosch PMF 10.8V
Children:
Bosch PMF 10.8V - only machine
Bosch PMF 10.8V - package 1
Bosch PMF 10.8V - package 2
Catproduct settings:
Default layout: main.php
Children layout: radio.php
Other products are added as attached products in Catproduct (at the bottom).
For checkboxes layout, you need to download checkboxes group layout and copy it to group folder inside catproduct.
Then you need to set layout in attached products settings to checkbox
All other things are mostly the same as for any catproduct example. You can see more explanations on default captorduct demos.
If you have more questions, please ask.
Best Regards,
Maja
