Hi, I'm totally new to Seblod and I have been trying to learn it via tutorials. One of the tutorials found in Youtube (https://www.youtube.com/watch?v=qJfscgEKwvU&list=PLruYrlqNC8kityXVoI43m5KefpAeUz-Fv&index=5), James Morrell shows how to link or establish relationship between one Content Type to another one, by selecting the Live option to 'Var (Int)'. The problem is I don't see it in Seblod 3.17.5. In the tutorial, it is not mentioned what plugin to use. Could anyone help me to point to the direction how to enable it or which plugin to use? Thank you.
