css positioning

[monty 187]

Hi Guys,Im sure some1 has done this before so here goes, i am trying to create a dropdown menu from a menu on my page. I am going to do this by setting the display option when a mouse is moved over the menu option. I am currently trying to position the menu below the drop menu on the page. my problem is when i resize the browser window the position of the drop menu changes. Here is the code i use to position it,

#dropmenu{	position:absolute;	left:700px;	top:40px;}

Thanks a million guyz!!

Also guys is it possible to have the menu set to <display:none> and then have it appear when hovered over? If i can get this going maybe i can alter it to appear when another element has been hovered over, ie hovering over one menu element makes the other element appear.
