Possible to use horizontal tabs within vertical tabs?

Possible to use horizontal tabs within vertical tabs?

I'm trying to use horizontal tabs within vertical tabs. The JQuery UI
docs are no help. I've tried following an example I found where vtabs
are used inside of htabs, but it doesn't work either. Here is my
code:
$(function(){
$("#verttabs").tabs().addClass('ui-tabs-vertical ui-
helper-clearfix');
$("#verttabs li").removeClass('ui-corner-top').addClass
('ui-corner-left');
$("#htabs-1").tabs().removeClass('ui-tabs-vertical ui-
helper-clearfix');
                $("#htabs-1").tabs().addClass('ui-tabs');
$("#htabs-1 li").removeClass('ui-corner-left').addClass
('ui-corner-top');
});
I want htabs-1 to be a horizontal tab inside one of the verttabs.
I've tried all variations on the above code I could think of, but none
of the work.
Is it possible to use htabs inside of vertical tabs?
