Wizard has implemented special mark for summary step. If you add to your step element the attribute data-sf-step="summary", then wizard will search for double curly brackets {{nameOfInput}} and replace this brackets with value of form. You can use default value after pipe character, if input isn't filled. For example {{inputName|Paula}} causes, that everybody who doesn't fill input with name inputName will be Paula. You can also add the attribut data-sf-text="Alternative" to specific inputs, that means if input is checked, then Alternative will be shown in summary step. These are only basic summary functions what wizard can provide. If you need more sophisticated summary, you have to code it by your self.
