I've read the documentation on hooks and filters, but it seems a bit sparse. Where can I find the full list of hooks available in Gravity Forms and a general view of how to use them.
I want to change the way a set of radio buttons is displayed - by putting a line through an option if that option has already been 'taken' by someone. No idea how to implement this. Where can I find info on hooks specifically and the structure of the GF database so that I know what I am looking for.
