# Custom Field Choice Sets Single- and multi-selection [custom fields documentation](../../customization/custom-fields.md) must define a set of valid choices from which the user may choose when defining the field value. These choices are defined as sets that may be reused among multiple custom fields. ## Fields ### Name The human-friendly name of the choice set. ### Extra Choices The list of valid choices, entered as a comma-separated list. ### Order Alphabetically If enabled, the choices list will be automatically ordered alphabetically. If disabled, choices will appear in the order in which they were defined.
