Allow the user to uncheck all radio buttons in the set
When the user selects one of the options in a radio button element, he can no longer disable both. Our user needs to leave the choices in a radio button set blank.
Thank you.

Introduce a blank option and make it as default option so your users can select a value or leave it blank. Unlike checkbox, one of the radio buttons must be checked.

Hi Alexander, Radio buttons are used when there is a list of options that are mutually exclusive and the user must select one choice. If you want user to be able to leave it blank, you can use checkboxes. Another solution is to add a third option for example called 'select' and clear the value blank. You can make this default option. More information about form elements can be found at http://howto.caspio.com/datapages/forms/form-element-types/
