Collapsible screen type elements

Currently within the project I work on we make use of the detail tiles on the side of most of our subjects. Like this:

What I would like to be able is to collapse this element the the right side of the application so the screen has more room to word with. It should work the same way as the menu does, like I can open it by clicking on or hovering over it.

This could also be implemented for elements like the Tab containers.
