How it works
The main logic here lives between form() method on our Resource and the create and edit functions
- Three different groups of checkboxes - Users, Groups, Positions
- Each group has a set of checkboxes that can't be mixed. For example, if you selected Users, you can't select any other group
- Each of the checkbox is reactive and generated real-time for the form.
- There is a hydration logic for the checkboxes, so that when you edit the form, the checkboxes are pre-selected.
- We will override the input format on both create and edit actions using
CreateTaskandEditTaskfiles to fit our new format and save relationships manually
Here's how that looks in our form() method:
