How do I change Menu Item Type Order?

Hi,

When You add a menu item you click "Menu Item Type" and get:

[attachment=1:3g7j2tus]<!-- ia1 -->Untitled-6.png<!-- ia1 -->[/attachment:3g7j2tus]

As we don't use articles, how do we hide it or remove it.

So, it looks more like this:

[attachment=0:3g7j2tus]<!-- ia0 -->Untitled-7.png<!-- ia0 -->[/attachment:3g7j2tus]

Any ideas which file to edit?

I don't recommend this, but you could change file

administrator/components/com_menus/models/menutypes.php

inside function getTypeOptions()

e.g. change:
$query->order('name ASC');
to:
$query->order('name DESC');

or even better, do some PHP manipulation after the DB query is executed
