Many to Many Item Relation Mapping


How to have many to many relation among items ?

Below is the many to many scenario ,
smartphone (e.g. iPhone 6) has repair parts list, from the parts list ,same loudspeaker part can be used across other iPhone Models also.

What are suggestions for the best design to do this ?

Is it available out of the box ?

You should add each spare/repair item separately. For now, there is no option to list them together. If they belong to same group, they will be listed in the group together.
