Folding bar (Like the charts), can it be used for other stuff? CRM Online

So basically I am trying to create a way on the account page to view our representatives assigned to the account. 

But I do love to keep the page neat and tidy, with minimal space used. 

So I thought maybe I can create a folding bar like how the charts work on the view of accounts. 
Ideally the bar could be accessed by pressing it and would show pictures of the team. 

I am relatively new to the CRM scene, so any tips or recommendations would be awesome! :)
