[IxDA Discuss] select exact number widget?

[lachica]

Hi Victor,

How about a pie chart that shows how many pieces you can possibly pick and
then allows the user to select directly from the graphic? For example, if
you want to allow the user to pick up to three items you would have a circle
divided into three pieces and they could select any or all of the pieces.

Best,
Julie
