+This block creates a variable with enumerated choices. \
+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.
+
+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.
