view.moveUp(id)
    view.moveUp(id,step);

    view.moveDown(id,step)
 
    view.moveTop(id)
 
    view.moveBottom(id)

//move to the position
    view.move(id, index);
//move to different view
    view.move(id, index, some_other_view);
    //or
    view.move(id, null, some_other_view);
 
//move to different view and change ID
//scenario can be necessary to prevent ID collision
    view.move(id, index, some_other_view, target_id);

ID of item is preserved while moving.

//make a copy of element
   var new_id = view.copy(source_id);
//make a copy at specific position
   var new_id = view.copy(source_id, index);
//make a copy in different view
   var new_id = view.copy(source_id, index, some_other_view);
   //or
   var new_id = view.copy(source_id, null , some_other_view);
 
//make a copy with defined ID
   view.copy(source_id, null, null, target_id);
   //or
   view.copy(source_id, index, null, target_id);
   //or
   view.copy(source_id, index, some_other_view, target_id);

method returns ID of copied item, which is auto-generated or can be specified as last parameter.
