 ## API
 
+### Properties
+
+Group (Optional): Used for dragging between lists. Set the group to the same value on both lists to enable.
+
+Handle (Optional): The CSS class you want the sortable to respect as the drag handle.

+OnRemove: The method to be called when an item is removed from a list. This method is useful for handling the drop even between multiple lists. Like `OnUpdate`, it expects `oldIndex` and `newIndex` parameters.
