Prestashop模块后台选项卡打开iframe

I am creating a prestashop 1.6 module. In the back office it creates a root tab and 4 child tabs. Each child tab has it's own controller which I have made and is all set up.

What I would like to do is have each of the child tab's controllers open an iframe in the back office. I would like the back office to wrap the iframe so it appears native like the typical prestashop back office forms. Is there a way to do this? I have done a lot of googling and nothing I have found has worked. Hoping someone here knows a solution!
