create submenus of a group of pages on different pages

Hello, I just installed admin page frame and I would like to know if you can create a submenu within a group of pages on different pages for example:

$ this-> addSubMenuItems (
training(
'title' => 'First page', // page title
'page_slug' => 'my_first_page', // page slug
'screen_icon' => 'https://lh5.googleusercontent.com/-vr0hu0pHcYo/UilDa_OwGYI/AAAAAAAABRg/29eid1MIBW0/s800/demo03_01_32x32.png',
'style' => array (
AdminPageFrameworkLoader_Registry :: $ sDirPath. '/css/code.css',
) // page screen icon for WP 3.7.x or lower
),
training(
'title' => 'Second page', // page title
'page_slug' => 'my_second_page', // page slug
'screen_icon' => 'https://lh5.googleusercontent.com/-vr0hu0pHcYo/UilDa_OwGYI/AAAAAAAABRg/29eid1MIBW0/s800/demo03_01_32x32.png' // page screen icon for WP 3.7.x or lower
), 

That the first page of the submenu is on a different page, to better organize the submenus.

I saw this example, but I don’t know how to do it for a group of pages
Example
and the other question is if you can add css file to the file

I hope you can help me, thanks in advance
