I wanted all the fields in my form to be required, however, I don't want to put a Field label even the asterisk sign

Through custom CSS you can make all the fields in your form required, and it doesn't display a label for the field or even the asterisk symbol.
Please check this documentation link: https://formnx.com/details/docs/getting-started... for the custom CSS code that you can use to hide the label of the Field and the asterisk symbol in your form.
