Allow for layout of data cards within forms

[Steelman70]

Currently it seems that data cards can only be placed sequentially one after the other in forms in a one-dimensional layout.  It would be really useful if we could define the layout of the data cards within the form more freely, to be able to create a two-dimensional layout.

This is also a thing I concern.

To custom form card, I think the only way to work with it is to use Custom API
