You can use css selectors to change the way that the menu tabs are displayed. The built-in control has several modes which wrap RadControls for ASP.NET AJAX like RadMenu, RadTabStript. RadPanelBar etc and each control has its own specific css selectors.
Of course another option is a custom control which uses RadMenu
. This would be the better option for me, because the custom control will give you control over all elements you want to display.
