Hello. I have a problem with collapse (group) rows.

I use this function:
$objPHPExcel->getActiveSheet()->getRowDimension($i)->setOutlineLevel(1);
..
$objPHPExcel->getActiveSheet()->getRowDimension($i+1)->setOutlineLevel(2);
But when I open file and expand root group, another groups opening too.

What should I do for open only clicked group without others?
