When using a Drupal Webform with CiviCRM it is possible to add a Null or 'Empty' option to a Select input box, if using a dropdown list. Is there a way to do the same thing if using radio buttons?

    If the field is not marked as Required then it can be left empty. Does that do what you need? – Aidan Aug 12 '20 at 9:32

No Required Radios example:

Alternatively in CiviCRM -> Custom Fields -> If you wanted to specifically record the 'none' option simply add it as an Option (Add Option) and it will automatically appear on your webform as an option as well!

  • Null seems to be following you lately @karing-semper-it ... – Demerit Aug 12 '20 at 16:23

  • This is on D7. I'm dealing with the field which selects Membership Types, where it defaults to the existing value if a Membership already exists, and I wanted an option for the user to turn it off. Required doesn't affect that, and adding an 'Empty' type isn't really what's wanted. I can add a separate button and uncheck it with JavaScript, but the server still defaults to the previous value unless there is an explicit alternative set. I guess I could try adding another radio with JS which returns a value the server doesn't understand, maybe try that later. – maynardsmith Aug 13 '20 at 1:26
  • it may help if you explain your scenario more thoroughly in your Question. eg scenario is a webform that allows for membership renewal but does not require it and the need is to prevent civi default behaviour of expecting someone to renew an existing membership – petednz - fuzion Aug 13 '20 at 20:03
  • the answer to which may be, add a field that says 'do you want to renew, add a membership or not', and then use Conditionals to set the Membership value (if that works. not tested) – petednz - fuzion Aug 13 '20 at 20:03
