Dropdown list and formatting

Currently my results from a multiple item dropdown list print as a comma delineated list in the output. I need them to print as a list of choices. I found some help topics but the are as clear as mud to me.
Could someone explain it for me again

Hi @Kathy_White

You can do this with the formatter option to tell Text Blaze how you want to separate its values. It previews like a single line, but when you insert the text, it'll be a bulleted list.

-{formmenu: default=Choice A; Choice B; Choice C; Choice D; name=topics reviewed; multiple=yes; formatter=x -> join(x, "\n- ")}
