jQuery UI across frames...

I have and index page which contains navigation and stuff, and inside same index page there is an iframe, where content is loaded without reloading his parent (index page). Now i was wondering is it possibile to load jQuery UI in index page, and use it inside iframe. Because index page never reloads, so jQuery UI wouldnt have to be loaded on every change od content...

I hope i managed to explane my problem clear enough...

Thanks in advance...
