please have a look this sample, which I cannot make the nested div #2.2 scrollable. Can anyone help it out? Thank you.
For this layout, there is a root grid div containing two divs (div #1 and div #2). Inside div #2 grid div, there is two divs (div #2.1 and div #2.2). The div #2.2 is an oversized yellow div which I want to scroll, but I cannot.
