I am using theme Prestige 7.3.0, and have tried to make multi-column, alphabetized vendor list with this example (https://gist.github.com/rseabrook/a9fd61fabacabb4b40a1d572bad834ca)
It didn’t work for my shop because the order wasn’t multi-column, but still alphabetized.
Is there any way to make the order as 3-column one?
