sm_list: Select multiple list constructor
In caldwellst/koborg: What the Package Does (One Line, Title Case)

'sm_list()' constructs a select multiple list object, where each entry in the list corresponds to the selected options for that survey row. Can be constructed from an existing list of character vectors or a character vector itself that will be turned into a list by splitting on spaces in the string.

sm_list(
  x = list(),
  relevant = NA,
  choice_names = NA,
  choice_labels = NA,
  q_name = NA,
  label = NA,
  constraint = NA,
  binary_sep = "/"
)
