thats one way of doing it, or have a close all and call the before you "open" the correct menu.

function change_it(itemID) {
closeEverything();
document.getElementById(itemId).style.display = 'inline';
}
function closeEverything() {
document.getElementById("menu1").style.display = 'none';
document.getElementById("menu2").style.display = 'none';
document.getElementById("menu3").style.display = 'none';
...
}

OR

you can close everything and open the item all within the same method.

function change_it(itemID) {
switch(itemID)
case 1:
   document.getElementById("menu1").style.display = 'inline';
   document.getElementById("menu2").style.display = 'none';
   document.getElementById("menu3").style.display = 'none';
case 2:
   document.getElementById("menu1").style.display = 'none';
   document.getElementById("menu2").style.display = 'inline';
   document.getElementById("menu3").style.display = 'none';
....

}

I'd do it the first way that I've listed with the close everything of the 3 options listed so far.
