I need to change the position of popup dynamically like when i show popup onmouse hover of hyperlink, popup always shows at bottom of the hyperlink, in this case when hyperlink is at end of the browser then more than half of the goes hide.

So, I need the popup position change according to the space, if the hyperlink is at end then popup show at top of the hyperlink otherwise at bottom.

How could i achieve this task ?
