In choice properties, you can decide your user is able to choose one or multiple options. For single choice, it normally knows as
Radio buttons in your form which only allows one selection. For multiple choices, it knows as
Checkboxes which allows multiple selections. You also can turn on an
Other Option to allow user input some text. When the submission is generated in PDF, those selected options are rendered to a
cross sign. The other option text is rendered as text if its option is marked as selected.
