Hell @devs,
I'm trying to implement the core multichoice as combined sub-type (I don't want the OU-one notation system, nor the checkboxes for UI). No problems on where to place my files, but I'm not really sure of what I need to keep / change from the original implementation, neither for combinable.php nor for renderer.php.
Do you have some tips to implement quickly the behaviour of a core type as combinable ? (I'm trying to do it, comparing the source files of 'gapselect' with 'combinable_gapselect' for example, but that's not the most efficient)
Cheers,
PS : it's gonna be an implementation for last combined version (build 2017061400)
