I have two frames which will fix width to cols when not framed together.
I want to frame the two child frames together so they scale with each other i.e. share the fill of the container), however when I frame them, the the original fix to col stops working.
Think of a persistent drawer and body with beside it. When the drawer disappears i want the body frame to fill that space and when the drawer is present, i want it to shrink to let it exist on the screen.
