Reference Set Selector (Checkbox) as a pluggable widget?

Has anyone worked on a Reference Set Selector (Checkbox) as a pluggable widget? I have a requirement to allow the reference set carry a flag that would show them but make them unselectable (greyed out) to reflect dependencies between them (Option 1a selected, Option 1b selectable. Option 1a not selected, Option 1b shown however not selectable). I am not into DOJO so extending the existing reference set selector widget is not really an option for me…

Hey there, sounds like a bit of a tree selector functionality, so maybe the Tree Node would work?


Otherwise you could play with having a list view and dynamic classes based on the selection and/or deselection of items. for example using a class for selected items and a class for not-selected items.
