In July, we [opened up discussion](/2006/07/18/default-radio-button-behavior/ “Default radio behavior”) on how we should handle radio buttons and the ability to have no default selection. Feedback from the community was fairly balanced, but in the end we decided to make it so that you *can* create radio buttons *without* a default selection. The reason we took out forced default selections is because we wanted to give as much flexibility to the Wufoo admin as possible. Now, you can create both an unselected radio group and a radio group that has a default selection.
Be sure to read about this change and others that went out in the Wufoo [1.0.5 update](http://www.wufoo.com/forums/viewtopic.php?id=31 “Wufoo 1.0.5”).
