Jquery And Yii Conflict

Hi @all

Urgent Help required.

I am a newbie to Yii. I am trying to implement an autocomplete field using yii. It works fine. But when I add a plugin for dropdown list, the file "jquery-ui-1.10.1.custom.js", needs to be added.This file is causing functionality prob to the autocomplete field. The autocomplete list can be retrived from d/b, but not able to select any option using arrow keys or mouse click. Any help will be appreciated.

Thanks in advance
