Ability to expand / collapse the Attachments macro like a page tree

A way to collapse the contents listed in the Attachments macro within Confluence.

I created a page with the 3-column page layout and put Attachment macros in each column. As the first attachment macro filled with doc's, it expands the page quite a bit. I was asked by the person I was designing it for if I could collapse the list of doc's to make it look neater.
