Create many to many Relationship with a specific fields in a Content type to taxonomy I am currently encounter a problem, I have one content type (Type) and two taxonomy needed to be link up, in that content type, I need to apply a many to many relationship among a field (Name: Core) and two taxonomy Terms (Such like below image), I would like to ask is there any method to implement this idea??
You will have to use entity_reference.


Add a field "Core" to your content type of entity reference. 
Then under "target type", choose "taxonomy term"
Under "entity selection" choose your vocabularies
On the next page set "Number of values" to "unlimited"
