Adding Widget to Header

similiar concept with the previous top menu but different code add this in functions.php or create new file meso-custom-functions.php in wp-content/

<?php
function meso_add_new_widget() {
register_sidebar(array(
    'name'=>__('Top Right Header', TEMPLATE_DOMAIN),
   	'id' => 'top-right-header',
	'description' => __( 'Top Right Header widget area', TEMPLATE_DOMAIN ),
	'before_widget' => '<div id="%1$s" class="widget %2$s">',
	'after_widget' => '</div>',
	'before_title' => '<p>',
	'after_title' => '</p>',
	));
}
add_action( 'widgets_init', 'meso_add_new_widget', 10 ); 

function meso_add_top_right_header_widget() {
if ( is_active_sidebar( 'top-right-header' ) ) {
dynamic_sidebar( 'top-right-header' );
}
}
add_action('bp_top_right_header','meso_add_top_right_header_widget');
?>

open header.php go to line 113 and add this

<?php do_action(‘bp_top_right_header’); ?>
