Using code almost verbatim from the manual
<body onload="hideMenus()">
function hideMenus() {
array_to_hide = $A($(''Links_Sub'').previousSiblings());
array_to_hide.each(Element.Hide);
}
Links_Sub and it''s previous siblings are submenus that need to hide
and appear on roll-over of other links. I''m keeping them shown in the
original CSS style and using hide here.
Testing this in firefox on a vista box, I''m getting: iterator is not a
function.
This is my first time using prototype, so it may be something easy to
fix.
Has anyone experienced this, can anyone provide assistance?

First of all, it''s Element.hide (lowercase)
Second, there''s a special enumerable method for invoking a method on a
collection of elements - http://prototypejs.org/api/enumerable/invoke
invoke
Third, there''s no need for $A, since previousSiblings() extends
elements
automatically.
Something like this ahould do it:
function hideMenus() {
$(''Links_Sub'').previousSiblings().invoke(''hide'');
}
P.S. In my recent post I explain how to solve such common thing as iterating
over menu items.
