The extra options that this plugin provides are:

• tree: (Array) list of tree items or (optionally asynchronous) function to obtain them; items are strings or objects with:

  • name: (String) to display in list; must provide this or value
  • value: (String) to put in answers hash; must provide this or name
  • short: (String) to display after selection
  • open: (Boolean) whether the item is expanded or collapsed
  • children: (Array or Function) list of child tree items or (optionally asynchronous) function to obtain them; function may return replacement item instead of just list of children

• onlyShowValid: (Boolean) if true, will only show valid items (if validate is provided). Default: false.

• hideChildrenOfValid: (Boolean) if true, will hide children of valid items (if validate is provided). Default: false.

• transformer: (Function) a hook function to transform the display of item's value (when name is not given).

• multiple: (Boolean) if true, will enable to select multiple items. Default: false.
