Controlling columns in layout

At the end of my app.layout I’m using style = {'columnCount' : 2}
But how can you control which components/figures end up on the left column vs. the right column?

I believe the content is distributed across the columns based on the size of the content, and you don’t have control over what ends up in which column.

You probably need to write some custom CSS, or you could try using something like dash-bootstrap-components to control the layout.
