How to add MH Slider below the Header?

1) In the Demo I can see the slider below the header but in widgets there is bo option. Is it because its the free version?

2) I managed to make a new widget area below the header, but when placing the MH Slider widget, it become huge. For now I have placed other widget. How can I make it smaller? please help me if you can.

The changes I maked are:
in index.php I placed:
<div style = ‘width: 100px;’>
<?php if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(“top_slider”) ) : ?>
</div>

in functions.php i placed:
if ( function_exists(‘register_sidebar’) )
register_sidebar(array(
‘name’ => ‘top_slider’,
‘before_widget’ => ‘</div>’,
‘after_widget’ => ‘<div id=”%1$s”>’,
‘before_title’ => ‘<h3>’,
‘after_title’ => ‘</h3>’,
)
);
