var checkboxGroup = CardService.newSelectionInput()
.setType(CardService.SelectionInputType.CHECK_BOX)
.setTitle("A group of checkboxes. Multiple selections are allowed.")
.setFieldName("checkbox_field")
.addItem("checkbox one title", "checkbox_one_value", false)
.addItem("checkbox two title", "checkbox_two_value", true)
.addItem("checkbox three title", "checkbox_three_value", true)
.setOnChangeAction(CardService.newAction()
.setFunctionName("handleCheckboxChange"));
var radioGroup = CardService.newSelectionInput()
.setType(CardService.SelectionInputType.RADIO_BUTTON)
.setTitle("A group of radio buttons. Only a single selection is allowed.")
.setFieldName("checkbox_field")
.addItem("radio button one title", "radio_one_value", true)
.addItem("radio button two title", "radio_two_value", false)
