Hi
@Sherry! Although we do recognize you are asking for a custom code solution, one suggestion would be to
add an iframe to your survey. An iframe will allow you to add any external website that you would like into a frame within your survey! You'll just have to check compatibility with the external site or forum you decide to use in your iframe. If you have any additional questions in regards to setting up your iframe, it might be a good idea to start a new thread! :)
I would also recommend reaching out to your organization, as they may be able to provide advice or any internal resources to help you get started!
