Selecting a dropdown item from another module

[REByers]

We have a new drop down field int he contracts module called 'Contract Type'.

We want to have a link field in the Cases module so that when a user selects an account the Contract type field (related to the slected account) appears in the case record when the contract is active.

There may be more than 1 active contract for an account at any one time as well.

How is it best to do this?

You need to implement an ajax feature under account_id onchange event.
This ajax feature (php script at server side invoked by a javascript at the client side) needs to identify all contract types related to the selected account and fill a dropdown.
