===== Navigation =====

Dynamic topic based navigation using category. E.g., the navigation show menu for different category in blog app.
This is done by using blog menu. A more generic solution is preferred.

    show_menu_below_id

If you have set an id in the advanced settings of a page, you can display the submenu of this page with a template tag. For example, we have our blog page that is not displayed in the navigation and that has the id "blog":

    <ul>
    {% show_menu_below_id "blog" %}
    </ul>

You can give it the same optional parameters as show_menu:

    <ul>
    {% show_menu_below_id "blog" 0 100 100 100 "myapp/menu.html" %}
    </ul>
    
    {% show_menu_below_id "blog" 0 1 0 1 "new_theme/templates/includes/menu/navigation.html" %}

Unlike show_menu, however, soft roots will not affect the menu when using show_menu_below_id

==== Limit the Item and sorted Item List ====
We edit the menu template:
    vim new_theme/templates/includes/menu/navigation.html
