I am looking for a way to make a specific item inside a list to be not draggable which is implemented using the disabled property. But the items that are not disabled can still be dragged above it and that would change the order of the list; the feature I am looking for would FIX that item's index so its order cannot be changed.

For example I have a list that contains 5 items and I want the first item to always remain on top, so I will FIX that item and make it disabled, so now all other items below it can be dragged and moved around but that FIXED item will always remain at index 1/0. Same could be done for the last item as well.
