If you want your applicants to click 'I agree' to a list of terms and conditions before submitting, we have a best practice for how to do that with the OpenWater form builder.
First, open up your OpenWater form builder.
Add a Checkbox type to your submission form and remove all the values except for one, and label it 'I agree'. In the 'Details' box, type in the terms and conditions they should agree to.
Finally, make the field required. This will ensure that the applicant has to check the I agree box before submitting.
