{
    return item ? 3 : 0;
}

- (UITableViewCell *)treeView:(RATreeView *)treeView cellForItem:(id)item treeNodeInfo:(RATreeNodeInfo *)treeNodeInfo
{
   // create and configure cell for *item*
   return cell
}

- (id)treeView:(RATreeView *)treeView child:(NSInteger)index ofItem:(id)item
{
   return @(index);
