Grid: Auto-fit buttons

Trying to setup Auto-fit on a grid I use for buttons called .action-group.

See images below.

On mobile, the grid needs to stack vertically only if there is no room in its parent container.

This is how it’s setup.

How do I set up the grid to automatically wrap the buttons on to the next row when space is needed?
