When I add a product I would also like to list which other models a part might work with see this website for an example http://www.qualitycartridge.co.uk/44973536-44973535-44973534-44973533 under "OKI 44973536, 44973535, 44973534, 44973533 is guaranteed to work in the following printers" I need it where you can search for diffrent other compatible model numbers but the part still shows up how can i do this.
You would need a custom module for making this a automatic setup in your administration.
But it could be done manually with some hours of work and a dozen static blocks.
1) Create a static block, name, ex.: OKI 299 put in all models with text + a link.
2) Then add this static block in the description field on the product you wish.
Let me know if this helped you further
