Hi,
For the moment we do not propose several kind of checkout bar ; but it's something in our TODO list.
You will need to do it manually by editing the view "checkout | step".
In this view you will find some PHP code which generate the checkout bar, it starts from
if($this->display_checkout_bar){
And it ends at
}
if(empty($this->noform)){
You need to change the way that this content is generated, in order to display some elements before the checkout content and some, after.
It requires some PHP/development skills.
Regards,
