How can i remove the sliding frame action from a specific sub-page or all sub-pages?

1) You can use “page without animation” page template to create a full width page without animation.

2) To remove animation from all inner pages go to Appearance->Editor and open scripts.php (includes/scripts.php) file. Find the following code, delete it and click on “update file” button (Be careful and don’t change any other thing).

if ( !is_page_template('homepage.php') && !is_page_template('without-animation.php') && !is_page_template('page-with-sidebar-without-animation.php')) { wp_enqueue_script('innerjs', get_template_directory_uri() . '/js/innerpage.js','','',true);
}
