hide sidebar on some pages

Hello,

How can i hide the sidebar on some pages? do i need to use some shortcode or something ?

Ok...i've figured it out myself...

1) i had to create a new template (e.g.: no_sidebars.php) and place it at the root of diablofun theme.
2) inside of no_sidebars.php i placed this:

<?php
	/*Template Name: No Sidebar*/
?>

<?php
	get_header();
?>

<?php 
	global $SMTheme;
	
	get_header();
?>
			
			
			<?php get_template_part('theloop'); ?>
			

<?php
	get_footer();
?>

3) Then i edited my page and and i selected my new template "No Sidebar" and after publishing the page, the sidebar was gone for that page.

I hope this helps someone.
