Checklist multiple lines for one choice

Unfortunately, you cannot have multiple lines on each item in the Checklist widget. HTML tags will not work inside the widget. If you want we can resize each item in the widget using custom CSS. However, the whole option will be affected.

If you want, you can just use the normal Check Box field. In here, you can add <br> tag so that you can have multiple lines for each option.

Hope that helps. Thank you.
