Interface Choice

A single choice associated with a type of Item that supports choices, like CheckboxItem, ListItem, or MultipleChoiceItem.

// Create a new form and add a multiple-choice item.
var form = FormApp.create('Form Name');
var item = form.addMultipleChoiceItem();
item.setTitle('Do you prefer cats or dogs?')
    .setChoices([
        item.createChoice('Cats', FormApp.PageNavigationType.CONTINUE),
        item.createChoice('Dogs', FormApp.PageNavigationType.RESTART)
    ]);

// Add another page because navigation has no effect on the last page.
form.addPageBreakItem().setTitle('You chose well!');

// Log the navigation types that each choice results in.
var choices = item.getChoices();
for (var i = 0; i < choices.length; i++) {
Logger.log('If the respondent chooses "%s", the form will %s.',
           choices[i].getValue(),
           choices[i].getPageNavigationType());
}
