Relations

[patblom]

Is it possible to get many-to-many relations in one editfield at each entity when you relate for example Contact to Contact? (Not divided into incomming and outgoing relations)

And the other question. Is it possible to set properties on a relation without using an entity between?

You can create many-to-many relations between the same entity, but it is divided into the left and the right sides.
Fields and links could have an option "additionalColumns". As example open application/Espo/Modules/Crm/Resources/metadata/entityDefs/Opportunity.json, contacts field and link
