• QR code
  Add QR codes to personalize or uniquely identify a form.
• ContainerConfig
  This element is used to break content into columns and to add a footer to the form.
• BlockConfig
  This element is used to organize other elements in container columns.
• ContentConfig
  This element is used to add a line of text to the parent element. Can only be used inside other elements.
• EmptyLineConfig
  This element is used to add vertical spacing between elements.
• ParagraphConfig
  This element is used to combine text and images.
• InputGroup
  This element is used to insert personalized information, such as the respondent’s name or email, into the form.
• PageConfig
