creating sub menus?

[Andrew Wooldridge]

I want to create a menu item that has sub menu items - is this
possible? It seems better than adding a bunch of top level menu items
just for one "app".

Try the "menu" property of menuitems:

var menuitem = {
label: "Submenu",
menu: new jetpack.Menu([
{ label: "Another Submenu!", menu: new jetpack.Menu(...) }
])
};
jetpack.menu.set(menuitem);

Is there any reason why we have to make that extra object? Should this be able to work too?

var menuitem = {
  label: "Submenu",

  menu: [

    { label: "Another Submenu!", menu: new jetpack.Menu(...) }
  ]

};
jetpack.menu.set(menuitem);

Yeah, I've had the same thought. The reason the jetpack.Menu
constructor exists is because menus have specialized methods. So you
can for example:

var myMenu = new jetpack.Menu();
myMenu.add("foo");
jetpack.menu.set({ label: "My Menu", menu: myMenu });

We could just box the |menu| value if it's not already a jetpack.Menu,
but I chose not to because in one sense it's more complex: Sometimes
you have to write jetpack.Menu, sometimes you don't. But you're right,
it does make code more terse if you don't have to write it.

What do you think?

I think of it as graceful upgradation; only when you need the power do you level-up the syntax.

I don't think it would be more complex, it's like what String.replace
does, so it's a concept a js developer would be used to.
