<doc>
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.
