Hi,

header.php:
function my_widgets_init() {
register_sidebar( array(
‘name’ => __( ‘Header Area’, ‘your-theme’ ),
‘id’ => ‘sidebar-2’,
‘description’ => __( ‘An optional widget area for your site header’, ‘your-theme’ ),
‘before_widget’ => ‘<div id=”%1$s” class=”headwidget %2$s”>’,
‘after_widget’ => “</div>”,
‘before_title’ => ‘<h3>’,
‘after_title’ => ‘</h3>’,
) );
}
add_action( ‘widgets_init’, ‘my_widgets_init’ );

function.php:
<?php if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(‘sidebar-2’) ) : ?>
<?php endif; ?>
