Question

… while still enabling it scroll?

I have a Spark List running in a mobile application. When I turn on horizontal scroll bars and then when I swipe as I use the application scroller bars fade in and then fade out. I would like them to always be invisible.

Inside your css file do this

s|List s|HScrollBar {
    skinClass: ClassReference("ScrollBarSkin");
    fixedThumbSize:true;
}
s|List s|VScrollBar {
    skinClass: ClassReference("ScrollBarSkin");
    fixedThumbSize:true;
} 

create a class like this

package 
{
    import spark.components.HScrollBar;
    import spark.skins.mobile.HScrollBarSkin;

    public class ScrollBarSkin extends HScrollBarSkin
    {
        public function ScrollBarSkin()
        {
            super();
            alpha = 0.0;
            visible = false;
        }

    }
}

All your list scroll bar will be invisible, hope this will help
