Expand / collapse details

I want to ask you for suggestions about expanding and collapsing some details from a document. I have a link for the prototype, just press show details/ hide details. Do you have any better idea for this action to hide and show details, instead of using a button? I already have 2 more buttons with reports and ... screenshots also attached. enter image description here
