 104 This block creates a variable with a drop down, radio buttons, or a button. \
 105 Leave the label blank to use the variable id as the label. \
 106 The value index is the index of a particular choice, \
 107 which defines the default choice when the flow graph starts. \
 108 The choices must be a list of possible values. \
 109 Leave labels empty to use the choices as the labels.
 110
 111 Use the Grid Position (row, column, row span, column span) to position the graphical element in the window.
