I hope someone will be able to give some starting steps as I have looked everywhere for examples of this scenario, but without luck.
Essentially, I have a view with JSON filter fields in it. I have added these fields using the Views JSON Source module. These filters are exposed, but Better Exposed Filters (BEF) doesn't appear to support JSON fields by default. So, when I try to select a widget in the Settings popup, I only get "Default" as an option. Because of this, my JSON filter field gets rendered as an auto-complete text field instead of a dropdown or checkboxes (the latter being my preference).

I'd like to add a Checkbox option to this list and I am wondering if someone could outline the steps to follow, from a) adding it to the widget list and b) the rendering in the view as checkboxes.
I am aware of this Select Option Filter patch provided for the JSON Views Source module, but this actually replaces the BEF Exposed form style together and doesn't work with combine search fields, unfortunately.

Any help is much appreciated.
