Make select dropdown submission redirect user to pageBrowser Info Environment
you could, for example, inside the on_form_submit method set up a listener for a select values questiontype that has (name)=>(email) pair, and then program an email send to that email.
So, some programming required, but for even a novice programmer, should be pretty easy to do exactly what you want with what is there combined with the proforms extend example package.
You would then open up /packages/proforms_extend_example/models/events/proforms_sbumit.php
Then add a listener for your select value pair in the onSubmit method.
Whenever a form is submitted, this event is fired, and there is a listener in the package that knows to pass the $form object into this onSubmit method.
From there you're golden. You can do whatever you want with the form object non-destructively (whenever we update the package, you don't have to worry about losing changes)
