I need help with installing a feature were customers can choose different panels that make on product. Example: Step 1: Choose 1 front panel out of 8 different panels shown in separate photos. Customer chooses front which pops up in one extra window. Step two: Choose 1 left panel. Customer chooses left panel out of 8 different panels shown in separate photos and that panel joins in the extra window. Step Three: Choose right panel and that panel also shows up in the pop up window. In the end I need the pop up window to show the finished product (6 Panels of which 3 are custom chosen) which then is what customer will order. You could say: Once he chose 3 Panels 3 other panels will automatically join OR these generic 3 panels are already in the pop up window from beginning. Now one click, and customer goes to check out with this custom made item. This feature is all I need to ad at this point. I simply don't know how to do it.
