The first item (item 0) on my list needs to be a title (e.g. Objects) or an action (e.g. "Select...") and when the user open the list, this item must not appear in the list, only the other items (object1, object2, object3, etc). I also need to define a css style to the item 0 (titlle/action) and another css style to the others. How can I do this?
