How can I make a div expand up instead of down if the vertical height increases?

I have a page with a title and some content. The header is a dynamic value and can have many different contents depending on the content.

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row.
