Yes, to ALL ULs. And I want to add method only to selected UL's -
those, which are instances of MyMenu.
So far the only working workaround I know is using global object -
MyMenuFactory:
MyMenuFactory = {
createMenu: function () {
var menu = new Element('ul');
menu.addItem = function () { ... }
}
}
The results are similar to what I want, but from the OOP point of view
it's wrong - and besides it uses one more name in global namespace (I
would like to avoid it)
@Nicolás Sanguinetti: to insert/update yes, but what if I want to
remove the menu later?
