Retrive Picklist of associated form field.

Hi,

On my  eloqua form i am having  two single line text fields and a single picklist field as shown below .

Countries PickList Field is attached to a Picklist called CountriesList which is having all the countries .

In below image i am generating these fields on my page dynamically using .net when page is load by using this api ( /assets/form/{0}?depth=complete ).So whenever i add or delete any field  i dont really need to edit my html page again and again.But my problem is  i am not able to load the associated Picklist field Choices to my html form dynamically.

Here is my html form below

I am getting all the fields and there details such as htmlName ,name,id ,etc ..   But my problem is i need to populate the associated picklist field values to my form as well .So how can i get the id or name of the picklist which is associated to my eloqua form's single picklist field which is Countries field in my case , so that i can get all the field values and i can bind it using this api(/assets/optionList/{0}?depth=complete).

Is there any way to get the forms field with associated picklist ID or Name ?

Thanks
