Wondering if anyone <cough>Sanford Whiteman </cough> has an example of appending custom HTML to a lightbox. I'd like to put program-specific information on the top of the lightbox, such as "Fill out this form to learn more about ABC..."
Also, why no prefill on Lightbox forms embedded on a Marketo LP?
This is kind of a dealbreaker for using the Lightbox function. It might be better to replicate with CSS.
