A couple new settings have been added to Formstack fields. Both of these can be found under the field settings on the field design page.
For checkboxes and radio buttons, you can automatically add an “Other” field. Selecting this will also display a text field next to the “Other” option on the form to allow a user to type in free-form text.
For checkboxes and radio buttons you can randomize the order of the options when they’re displayed on your form. This is helpful for surveys, quizzes and tests when you want to eliminate any bias introduced by the order of the options.
