Is there any method to collapse all opened subrows made with sub_row_ajax ?
You can use
grid.cells(i,j).open()
grid.cells(i,j).close()

There is no public method to collapse all sub_rows
You can try to use
grid._collapsMonolite();
but it not purposed for public usage, so it may have some side effects
