Make sure the div wrapping your tabs has the css class yui-navset and make sure that some outer div has the class yui-skin-sam

Hope it helps,

I did make a change recently to not include the yui stuff by default to reduce the number of css and js when they are not needed. If your page inherits from mojoBasePage, then in the OnInit, you can add this:

ScriptConfig.IncludeYuiTabs = true;
IncludeYuiTabsCss = true; 

or you can set thos properties directly on ScriptLoader and StyeSheetCombiner in your layout.master to make it load that stuff on every page.

Hope it helps,

Well use of YUI Panel doesn't equate always to use of YUI tabs, it only equates to using the yui-sam-skin.

I'm leaning more towards jQuery but using both YUI and jQuery leads to a lot of js and css added to the page. The only thing about the YUI tabs that I like better is that it behaves very well with nested tabs whereas jquery can get out of whack if you try to nest tabs. So I still am using the YUI tabs in admin pages but I'm generally not using it anymore for content since the jQuery tabs look nicer and have more skins. So it seems desireable by default to leave out the YUI tab stuff on public facing content system pages to keep tha pages lighter but its a little less of a concern on admin pages. But anyone who wants to use the YUI stuff in their content can easily set those properties on the ScriptLoader and StyleSheetCombiner and then it will be included on all pages. I'm just trying to improve the score using YSlow and Google PageSpeed.

Best,

Joe
