List Option

The List option allows the user to select one value from a predefined set of strings.

Description

In the jamovi UI, a List option is typically represented by a ComboBox (drop-down) or a set of RadioButtons.

Property	Type	Description
`name`	string	The unique name of the option.
`type`	string	Must be `List`.
`title`	string	The label displayed in the UI.
`options`	array	A list of strings representing the available choices.
`default`	string	The default selected value. If omitted, the first item in `options` is used.

In R, a List option is represented as a character string.

- name: hypothesis
  type: List
  title: Hypothesis
  options:
    - greater
    - less
    - unequal
  default: unequal

Access the value using self$options$name:

if (self$options$hypothesis == "greater") {
    # Perform one-tailed test
}
