    Leaving page warning message

    Is there a way to set up a warning that alerts a user when they try to leave the page if the form hasn't been submitted?

    Hi,

    Sorry but we do not have such feature available in the form builder. But, you can achieve that when you use your form source code and apply custom javascript that detect and pop up an alert message if the user leaves the page. The following might be of help.

    Let us know if we can be of further assistance.

    Regards!
