Would it be possible to preselect a dropdown item (in this case subject) when loading the form through a specific button or link.
Example: I click button A on page A that links to page C (contact page with the form on it) with subject A preselected in the form. I click button B on a page B that links to page C (contact page with the form on it) with subject A preselected in the form. etc..
So where the user is coming from (through which button) determines which subject is preselected.
The subject selection determines which fields are shown set via Logical condition within the form.
Maybe if the button is created in Quform (as a submit button) that some info can be send with it?
