Nevermind, I have identified the error of my ways! I was attempting to change the grid height before it was initialized with statusbar properties. My mistake.
Do not use any aggregates. Simply show a status bar(showstatusbar: true) and set whatever status bar height you’d like (height: x). There does not need to be any content in the status bar. Initialize the grid, then programmatically change the height value.
Thanks, that works. Doesn’t look too good when collapsed though, the box shadow doesn’t adjust to the header div. I’ll see if I can come up with something…
