scrolling a list in safari on iPad

I've had my iPad 2 since two weeks after it was released. I love it a lot. However, there are several issues of which i'm asking about one of them in this query. When I go to a site, www.wakerupper.com, to set up a wake up phone call,creating a call involves specifying a date, a time, a telephone to call. The issue at this point is the time. In Safari 5.05 on the Mac, if I click the current time value (which defaults to something if never set or to the most recent value otherwise), a dropdown appears with about a dozen or so times at 15 min intervals. I can scroll this list to further up or down. I use the mouse wheel, the track pad, or the scroll bars to do this. After I click the desired time, I can edit it to change if from 7:45 to 7:55 if that is my preference. So far so good and so far nothing to do with the iPad.

If I open this page in the iPad 2, it appears much the same. If I tap on the time, a similar drop down list appears. I can tap on any visible time to select it. However, I have found NO WAY to scroll the list up or down to go earlier than it offered or later than it offered. There is no scroll bar shown.

If this were the only site that had this problem, I would be going to that site support. But I've encounter other cases in iPad 2 Safari (which has been updated with all the latest software updates) a dorp down box with a limited number of choices appear and no means to scroll the list. I don't know HTML that well. I'm guessing that some sort of code is used to describe a list box and the two versions of Safari implement it differently but the iPad 2 Ssfari has left out the ability to scroll the drop down list.

First, can anyone describe how I could scroll the list in this sitatuion I may have missed it. If I put my finger on an item and slide it up or down, the entire screen tries to roll up or down not just the drop down list.

Is this due to the way the page is coded or is it a lack in the implemntation os some HTML feature in Safari for iPad2?

Thanks,
