Tabs don't display correctly after postback.

Tabs don't display correctly after postback.


I am a rookie with JQuery so please bear with me. I have an ASPX page with two tabs on it. The first tab has a couple ASP:Dropdownlists that do an auto postback. When the dropdown is selected and the page posts, when the page is refreshed, the content of both tabs are now on the same page.
 
Any thoughts?
