I want to display the simplecard (3rd column) below the previous simplecard as the image shows.

The code i now use is:

        Row::create()->sub([
            cards\01::create()->width(1/4),
            cards\02::create()->width(1/4), 
            cards\03::create()->width(1/4),
            cards\04::create()->width(1/4),
        ])

Any suggestion?
