If you see this page: http://www.avast.com
and mouseover the "Business" option on top, a menu underneath the top menu will show up, and it will show up sort of like in "slow motion"... if you mouseout, it disapears.
I tried to do the same by showing and hiding a DIV like this:
splay = 'block';"
play = 'none';"
This is what I have on the DIV
<div id="SubMenu" style="display:none;">
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<td height="150"> </td>
But it just shows and hide, which is fine.
My question is, how can I add that "motion" effect for the DIV to show up slowly instead of just show and hide?
