Any idea on how I can make a track to attach to a wall to have a cork board that is able to be slid up and down over a dry erase board. It would need to "lock" in order to keep it in place when slid up but then easily able to be unlocked to slide down when access to it is needed. I imagine the tracks would be something like the ones that slide drawers on Ikea desks etc...

sort of like this but perhaps vertically.

Horizontal ideas would help as well as a second option

Thoughts?
