Hello! I'm trying to append a hidden value that is dynamic upon a form submit. This value would be different depending on the landing page. From what I understand, you can not change a hidden value at the page level when using a global form and the native HubSpot form element.
I've found that I can easily append a hidden value (that can be changed at the page level) via the below javascript (which works for our HubSpot forms that are embedded on our WordPress pages).
However, I'm not sure how to achieve this with our HubSpot landing pages. We currently use the native HubSpot form element on our landing pages. Is there a way to add this additional javascript somehow?
