-------------------------------------
Great, it works!
As for now, I see no side effects. Autocompleters work smoothly as they did
when page height wasn't bigger than screen height.
> AutoCompleteTextField: Scrolling down the Choice Menu Only When the Bottom of
> the Menu Is Reached
> -------------------------------------------------------------------------------------------------

> Key: WICKET-1595
> URL: https://issues.apache.org/jira/browse/WICKET-1595
> Project: Wicket
> Issue Type: Improvement
> Components: wicket-extensions
> Affects Versions: 1.3.3
> Reporter: Andy Chu
>
> Currently, the AutoCompleteTextField will scroll the selected item to the top
> of the choice menu by the following code in the render method:
> if(selected==i) {
> classNames.push('selected');
> node.scrollIntoView(true);
> }
> However, I think it should be more user-friendly if the choice menu is only
> scrolled down for *one-item* when the bottom of the current menu is reached.
> Please refer to:
> http://www.dhtmlgoodies.com/scripts/ajax-dynamic-list/ajax-dynamic-list.html.
> This can be implemented by the following modification:
> if(selected==i) {
> classNames.push('selected');
> if (node.offsetTop >= element.offsetHeight) {
> element.scrollTop = node.offsetTop -
> element.offsetHeight + node.offsetHeight + 2 ;
> }
> if (node.offsetTop < element.offsetHeight) {
> element.scrollTop = 0;
> }
> }
> }
> Hope this feature can be added.
