-
- * Returns the list of options to be displayed for a field.
- *
- * Field types willing to enable one or several of the widgets defined in
- * options.module (select, radios/checkboxes, on/off checkbox) need to
- * implement this hook to specify the list of options to display in the
- * widgets.
- *
- * @param $field
- * The field definition.
- * @param $instance
- * The instance definition. It is recommended to only use instance level
- * properties to filter out values from a list defined by field level
- * properties.
- * @param $entity_type
- * The entity type the field is attached to.
- * @param $entity
- * The entity object the field is attached to, or NULL if no entity
- * exists (e.g. in field settings page).
- *
- * @return
- * The array of options for the field. Array keys are the values to be
- * stored, and should be of the data type (string, number...) expected by
- * the first 'column' for the field type. Array values are the labels to
- * display within the widgets. The labels should NOT be sanitized,
- * options.module takes care of sanitation according to the needs of each
- * widget. The HTML tags defined in _field_filter_xss_allowed_tags() are
- * allowed, other tags will be filtered.
