hide menus

[sfa]

Hi, I am a bit new to this. I created a page with animated slide in menus. The code creates tables, then hides them. Once thee menu items are clicked the menus show up in place. The problem is that when the page is laoding, the menu shows up on top for a while before being hidden. ANy suggestions as to what to do, maybe use some code that will not show the page untill it is all loaded?
Thanks
