documentation: |-
This block creates a variable with enumerated options. The gui widget is implemented as a combo box or radio button group. Leave the label blank to use the variable id as the label.
Choose the number of options available to your chooser. When the label is left blank, the option will be used as the label. Set the number of options to "list" to enter a single list of options and labels. When the labels is an empty list, the options will be used as the label.
The GUI hint can be used to position the widget within the application. The hint is of the form [tab_id@tab_index]: [row, col, row_span, col_span]. Both the tab specification and the grid position are optional.
