Get i18n translation from user via admin panel

I'm using the i18nnuxt module to have two language modes in my application. Currently I have two .js files that store translation key, value pairs. Problem If after some time the user decides that some translations need to be changed, I have to update them in the mentioned .js files and rebuild and deploy the app again! Ideal solution I'm wondering if there is a way to provide the user with a list of translation variables and their values in the admin panel so that they can change the values via API calls whenever they see fit? Any ideas on how to handle this would be greatly appreciated

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. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
