Multiple choice (Checkbox)

The "Multiple choice (Checkbox)" element enables respondents to choose one or more out of multiple options. If you want respondents to only select one option, consider using the "Single choice (Radio)" field instead.

You can add as many options as you need while creating or editing the field. To pre-select any of the options, add |* (Pipe and Asterisk) directly behind the value. So for example, Option B|* would make it pre-selected when viewing the form.
