item selected style for AW.Templates.Combo

I am changing my AW.UI.Combo to AW.Templates.Combo. I used a style on selected item as following:

.aw-frame-template .aw-items-selected {color: #fff; background: #316ac5;}

It works fine on UI.Combo, but the background style doesn’t work on Templates.Combo. How can I set a style for selected item of AW.Templates.Combo? Where is the style reference in AW documentation?

I am using 2.5.2 full version on XP, IE7.

Thanks,

On the above post, I actually mean "AW.UI.List" when I use "AW.Templates.Combo".
