For my users, I need them to be able to have both radio buttons and checkboxes in the categories when posting.
I have seen a solution to make the checkboxes when selecting a category radio buttons, so that a user can only ever choose 1 category. However, I have a scenario where two categories are mutually exclusive and the rest are a free for all.
So, the user MUST choose between category A/B. But can then have free choice of categories C/D/E/F/G/H, ETC
Is there a way to do this?
