We've recently released a beta version of a new form editor tool. The new editor has several new features for HubSpot users building forms and embedding them onto the HubSpot CMS and external pages
It's important to note that forms built using this new editor do not support the existing developer features that can be used with forms created with the legacy form editor. These features include:
Any other custom code written to work with older forms should not be expected to work with forms built using the new editor. As the code for new forms is still being developed, we do not recommend writing code to work with new forms at this time.
Existing forms will continue to function as they previously have. If you need to use any of these developer features, you should continue to use the legacy editor for new forms for the time being.
Developer features similar to the existing features for legacy forms are planned to be supported for forms created with the new editor in a future update.
