We already use "theme" to show related items for a product but we have a requirement to also show other products that a customer might need.
To make this clearer an example is as follows:
Customer looks at a wall light and in "theme" we have the matching ceiling light, table lamp, floor lamp etc.
We ALSO want to show them light bulbs that would suit the light they are looking at. Is there a way to implement this? Its a bit like a theme but its a one way relationship ie if they look at a light fitting we want to just show the suitable light bulbs(s) but if they are looking at a light bulb we wouldn't want to show the thousands of lights it would fit.
Can we do this?
