Implement a new behavior to allow saving repeaters into json columns

This trait is not intended to replace main repeaters but to give a quick and easy alternative for simple elements where creating a new table might be an overkill.
Simply define an array with repeater names on your repository:

protected $jsonRepeaters = [ 'REPEATER_NAME_1', 'REPEATER_NAME_2', ... ]
