I would like the main grid of my dash app to be made of three main components:
____________
|__1___|_2_|
|____3_____|
Furthermore, I’d like to be able to adjust the row heights between 1/2 and 3 and the column widths between 1 and 2 with mouse drag and drop and that the content responds to it so it can adjust its width/height. So far I could not find a feature in dash that works just like that.
