Getters with pinia cannot load

With pinia on VueJS, I use a store to store my licenses, and the licenses have a number that references the project. Lists of items with information are located in other stores.

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.

However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
