Add Accordion in Order-Detail page

[Shellanza]

Hi there,

I'm getting a bit crazy to add an accordion into my order detail page.

 

I tried to add the scripts files into header.tpl... no luck

I tried to add the code directly in order-detail.tpl... no luck again...

 

I saw that in some way there is the possibility to add this: $this->context->controller->addJS(library); But if I do in controller then what I have to write in TPL to let the accordion work?

 

Anyway the base I'm starting from is this:

Thanks in advance,
