I need to add a custom attribute called ids to my gravityform <form> tag, so it will come out like:
<form method='post' enctype='multipart/form-data' id='gform_3' ids='3,2' class='lead-gen' action='/test-page/'>
Optimally, I would like this to be as easy as a shortcode like
[gravityform id=1 ids='3,2']
I'd really appreciate it if anybody has any ideas for how this could be achieved. I see that there's a gform_form_tag filter, but I'm not exactly sure how to use it to add an attribute.
