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