<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.
Use the Notebook Param (notebook-id, page-index) to place the graphical element inside of a notebook page.
