Instead of using an anchor to scroll like the example you gave you can scroll like this, for example to scroll to the bottom of a div:

$("#mydiv").animate({ scrollTop: $('#mydiv')[0].scrollHeight}, 1000);

To scroll to an item in the div you can find the position to scroll to in a number of ways, there's a good discussion here:
