I have created a custom field type which works as a dropdown and choice value is populated programatically. This field works perfectly without any issue. Now I want to use Jquery and create a cascading dropdown. I have implemented this before and it works
for OOTB lookup columns and Choice column but its not working for my field.
I have use codeplex Spservice Jquery .

Please let me know, If I need to do some more settings make it work for my own created custom field.
