Simple Wordpress Sidebar Navigation

Hi, We have a WordPress website. We use Cardamon theme. I need a navigation menu on the sidebar. The theme allows us to make multiple sidebars widget. So we dont have any problem. We have like 7 main pages and 30 subpages. We already made all the pages and sidebar menu bar using jquery-vertical-accordion-menu plugin. What clients want is: When someone click on a subpage through the sidebar navigation, The button or the link of that particular page should be highlighted (or disabled) in the sidebar showing that the visitor is already on that page. I am a web designer my self and I have built all the menus already. What you need to do: Make what the client is asking for according to explanation above. You can use a different plugin or you can make it handmade. You have to make this ready in 48 hours. Lesser bid, better chance. Thanks,
