Choose menu in circles main page

Hi there,

I’m progressing in the customization of my spun theme website.

I created a child theme.
I added the line in index.php to show pages instead of posts in the circle main page.

Now I would like to select the pages I want to show in the circles (I don’t want to show all my pages created)

I created a specific menu with the pages I would like to show in the circle, which I named menu_main

Should I add something in the index.php
after <?php query_posts(‘post_type=page’); ?>
selection only menu_main …

But how ???
Thanks for your help !
