Is it also possible to dynamically pre-populate the "new" List field?
It's no problem to do this with checkboxes or any other input type, but I can't find the "format" for the "choices" array items of this List field.
Any help would be appreciated :)
Can you post a use case for this? It sounds interesting. I will have one of the developers take a look at it.

Well, in this case I want to use it for a wishlist, but I guess you also can use it for a kind e-commerce solution.
So I have a bunch of products, and I'd like to display them in a GF list, with product name in column A and the quantity in column B. The product names have to be pre-populated (based on the contents of the wishlist). The quantity can be entered by the user.
As far as I can see the (unserialized) "format" of the list data array (after submitting) is the following:
Array
(
[0] => Array
(
[Product] =>
[Quantity] => 200
)
[1] => Array
(
[Product] => Product 2
[Quantity] => 400
)
[2] => Array
(
[Product] => Product 3
[Quantity] => 300
)
)However, I can't use this same format when populating the "choices" array in the gform_pre_render filter. So it would be great if we can :)
any other solutions are fine too, but I think it's the easiest if the format stays the same.
One backdraw however: for this method you need to know the exact name of the columns to use it for the array keys. Maybe it's better to just map it to a regular index.
You can pre-populate list field using the gform_field_value_$parameter_name filter.
Following is a sample snippet that will help you with the data format. This example assumes you used "list" as the parameter name for that field.
add_filter("gform_field_value_list", "populate_list");
function populate_list($value){
return array("row 1 - col1","row 1 - col2", "row 1 - col3",
"row 2 - col1", "row 2 - col2", "row 2 - col3",
"row 3 - col1", "row 3 - col2", "row 3 - col3");
}Thank you for the update. Glad that worked out.
