Visibility (Public / Private)
Choose whether anyone with the link can fill out a form or whether respondents must sign in first, and switch a form between the two at any time.
Embedding a Form
Copy a form's embed code from the Share Form dialog, paste it into your own web page, and choose how the form sizes itself inside your layout.
One Response Per Person
Turn on Limit one per user so each signed-in respondent can submit a form only once, and understand why the setting is permanent.
