Invisible Form Field Question

[Anonymous]

I want lead source information for all people who fill out a certain form to be auto-filled upon form completion. This field would be invisibile. How can I create an invisibile field in a form and automatically populate that field with a specific lead source?

Thanks!

Hi Stephen, 

You would set the form field as hidden:

And then you can populate it's value in a few ways -- manually setting a default, grabbing a value from a URL parameter or from a cookie.
