Kindly use ReferenceSetSelector widget
need in horizontal values with comas, please help
output
require in horizontal values with comas and getting error when I am closing
The error is occuring because you have one to many relation with the entiy where the values are stored, it needs to be many-many.
Regarding the display horizontal separated by commas, this can’t be done with this widget
I have changed to many-many relationship, but still I am facing same error.
