jquery UI tabs fx options

I have two tabs. This, I do not want to change.

What I do want to chang开发者_如何转开发e is the fx option or write a function in the select event.

  select: function(event, ui) { slide 'ui.panel' left or right; return false; }

When I execute this code, nothing happens.

I want to simply slide the left div from left in and the right div from right in.

Any suggestions?
