I have a Custom Object called `Opportunity_carset`.the related list of `Opportunity Carset` Object is `Service`.
The `Opportunity Carse` Object has two fields.
1. Model
2. Version
- The Service object has some Picklist Field called `CodeLabel`
- Model and Version values from "Opportunity Carset" are sent as parameter to webservice class to retrieve the "service" Object Custom Picklist values.
**My scenario:**
Whenever am creating the "Service" record by clicking "New Service" from realted list of "Opportunity carset" Object,the Custom Picklist values should be displayed in Service Object.
Here,
I have created a apex class which take the Model and Version values and will give the custom Picklist values.

This class will return the Picklist Options.Using MetaDataApi I can update the picklist field values in"Service" object.But this all to be happen while creating a record from Relatedlist.Give me some Idea!!!
