How to layout using fields.markdoc now fields.document is deprecated?

[devnomic]

It also seems now layout only read the first array only? i cannot add multiple layout. when i click the layout button in toolbar, it always make two columns, there is no dropdown menu to choose 2 or 3 columns (if i remember correctly in the old version there is a dropdown menu when layout button clicked?).

 layouts: [
            [1, 1], //only have this layout
            [1, 1, 1],
          ],
