Features request: limited dragging range.

[AverageChau]

So my list have 2 section: pinned and regular. All pinned items is on the beginning of the list, the regular item is the rest. I would like when user drag the pinned item, the pinned item can not move out of the pinned section. It is the same with the regular section.

You can return false from reorder callback if item gets reordered out of its section.
