Yes it is possible to show the featured slider in every page,
Let’s see how to add Slider in Every Page –
For this you need to go in your code editor so that you can modify some code in php template.
To add slider to all full width pages,
Go to > Dashboard > Appearance > Editor
Scroll down a bit and find Full Width Page Template (page-full.php) in the left sidebar of your screen.
Open it and just after this line of code
<?php get_header(); ?>
Add this line
<?php if ( get_option('chameleon_featured') == 'on') get_template_part('includes/featured'); ?>
It will add the featured slider in every page.
