Open dynamic html page as layer when onmouseover

Hi Gurus,

Please find the attached html that i am working on. this has 3 columns and the 3rd column is ‘Show Comments’ link. when I hover the link it should display the html page on top my existing page like a tooltip.

For Example:
In this forum, when hovered on each topic, the topic description is displayed as tool-tip.

can anyone shed some light?

Thanks!

any one there can throw some light? Thanks!
