Should it be possible to use Columns and sections within blocks?

[thePhrase]

I want to structure my screen to improve readability. But whatever I tried with adding a columns or sections, it shows me empty blocks in the panel.
Can it be done? How can I use columns within the block?
( I now read that in sep 2021 it was not possible yet)

This is my working blueprint without columns.
I want to make a column for the field ‘uitzondering’, it should be on the right and the other fields should be placed to the left of this field.

No, columns or sections are not available within block definitions. All you can use is tabs.

I found a way to position the fieldset to the right of the other fields.
In my case this worked:

I made a custom css for the panel and added the css for the grid-column to span more rows:

.k-column:has(.k-field-name-uitzondering) {
  grid-row: span 3;
}

The field is called ‘uitzondering’ so Kirby is adding a class .k-field-name-uitzondering to it. Now I can hit the parent of this field with :has() and add the span to it.

The code is not elegant, the panel now is.
