Custom Fields with Secondary Drop Down Options
Does anyone know of a solution to create multiple layers of single select options in the custom fields.
e.g. I select "Outbound Marketing" in a Custom field called Source.
Once I select this a second custom field called Secondary Source gives me the choice of Email, Linkedin, Cold Call, etc.
But if I select a different option in the original field Source, the options in Secondary Source are different.
I hope this makes sense, any advice very much appreciated!
