The undesired layout after I save the menu:
It does not matter what order I out the parent menus. I also made all of the categories first level categories, but that did not help either.
It would be nice if when you added a category and it's sub-categories, the sub-categories woud automatically display as child-menus of the parent category in the menu layout. As it is now, you have to manually order the sub-menus.
And as I have noted in a previous post, the full content of my blog is in the source code of the menu page. I copied the source to text editor and saved it. It was 1.1M with 120 posts. All of the text from every post was in the menu page source code.
