I'm creating a form where I wan't to populate a dropdown list with values from custom fields, in this case we're talking about dates.
I have a list of dates for the post as custom fields, and now I wan't to be able to generate a dropdown in the form for the user to choose a date from.
I've looked into the Gform_field_value_$parameter_name filter, but that doesn't seem to apply to actually adding "option => value" combinations to the dropdown, or am I missing something? No matter what I try, the dropdown still only displayes the choices that are set for the form field in the WP settings.
Extremely grateful for any assistance!
