I'm selling personalised posters online.
Looking desperately for an app which will enable me to add a cross-sell pop-up to add a frame to the selected poster size.
Frames come in 10 different materials in 5 different sizes.
Let's say :
Poster 1 selected - size 70cmx100cm
then pop-up showing with all frames materials variant RELATED to size 70cmx100cm when pressing ADD TO CART or BUY NOW. (please see screenshot of an example here)
I have tried many options (many cross-sell apps that ask the customer to re-select the frame size again to match the poster)
Help, help, help please
