Literal List Values
To provide a list of literal valid values, you add the macro metadata element <type> to the corresponding <parameter> and set the datatype to enum. Add <list> as a child of <type>:
You then define the valid values as a simple string with values separated by commas using the <values> element inside <list>. With this configuration, the values you supply are also the labels that users see in the list:
If the values are not self-explanatory or you simply want to provide alternate labels, use a set of <option> elements rather than <values>.
Define the label to show in the label attribute and the value to send to the macro as the value of <option>:
