Seeking a solution in Bootstrap 4 for achieving the placement of 3 columns in one row, where the content in the first column dictates that the other two columns should be displayed alongside it. Bootstrap 4 utilizes Flex to manage rows and columns. Please refrain from suggesting solutions involving splitting Col1 into one container and Col2 and Col3 into another. I require flexibility to adjust positions based on column width as I work with various view modes. For example, if Col3 = col-12, it should appear below Col1 and Col2.
(Just an FYI, this feature worked smoothly in Bootstrap 3 due to floating elements and % column width).
