Hello Logan,
On
the following Dojo example you could find a Scheduler implementation, where the discussed approach is implemented. With it, the DropDownList in the editor template is being successfully populated based on the checked fields for the resources.
To achieve the desired result, I have made a few modifications:
1) Added the required data-x attributes to the checkboxes (as per the code sample provided):
2) Modified the edit function accordingly:
Regards,
Dimitar
