    I have a relationship between two CPTs. CPT-A has two terms in a taxonomy, let's call those "one" and "many" and there would only be one or the other. If CPT-1 has term "one", I want to set the max items of CPT-B to "1" and if the term is "many" I want to set the max items of CPT-B to unlimited (blank). How would I do this? There do not appear to be conditions or toggles for relationship fields.

    Hello Keith,

    MB Relationships doesn't support an option to set the max connection based on the taxonomy. I think it is possible but you need to create a custom code to do that. However, it is beyond our scope of support. You can contact an expert developer to help you in this case.

    Thank you for the info, Peter! If the taxonomy wasn't a part of this equation...is there *another* way to ensure that when choosing associated CPT-Bs (from CPT-A), that the user is able only choose one, and conversely, be able to choose unlimited CPT-As (from CPT-B)? If there is a video tutorial on how this sort of thing works, please share a link...still learning...

    In the builder, you can use the setting Max items in the field settings tab, screenshot https://imgur.com/isiuiHQ

    If you use the code, it is the setting max_clone. Please follow the documentation
