I'm building a fieldtype plugin that is essentially planned to be an extension of the 'Grid' fieldtype. I can see in the docs how you create a new fieldtype to be used inside of a 'Grid' but that's not what I want to do. I'm looking to create a plugin that essentially takes the functionality of a grid but with custom fields already inside.
Is there a way to do this? I'm using EE 3.4.7
