I know there have been a lot of posts about custom post types and taxonomies, but I can't find anything about what I'm after.
I've just read this topic here: http://forum.gravityhelp.com/topic/custom-taxonomies
It is similar to what I want, but my form needs to SELECT boxes of different taxonomies (for Listing Category, and Listing Location) -- (as in, not tag styles). I'm a bit lost how to do this, as I presume it uses another hook apart from gform_post_data and gform_post_submission?
Not particularly bothered how hacked it is, but it'd be great if there's a solution for this.
