The community member has an array within a collection and wants to append a comma to all items except the last one, and is wondering if this can be done within the expression editor. The comments suggest that this is more about conditionally rendering content, and that the community member could try using backend logic or client-side JavaScript to achieve the desired result. There is no explicitly marked answer.
I have an array within a collection. I want the items to be appended with a comma... all except the last one. Can I do this within the expression editor?
