Tabbar and the zIndex...

I need to know if is possible to change the zIndex, without change js source code.

It is possible, but i need to know what exactly element do you want to modify?
And will try to suggest you.

I needed to modify the z Index because if you put the tabbar control into jquery-window, yo can’t to click the elements into tabs.
However, i found a solution. I get the window zIndex and increment the tabbar zindex whit it.
Thanks for all.

Yes, it is reached by setting of certain css rules.
