Checkbox layout – 2 columns nonsense

I have Checkboxes: Choice Layout: 2 Columns.
For example:
Apples – MacIntosh ………… Apples – Royal Gala
Apples – Granny Smith ……. Oranges – Tangerines
Oranges – Clementines ……. Bananas

Option 2 should be below option 1, not in column 2,
i.e. options should be laid out vertically not horizontally:
Apples – MacIntosh ………… Oranges – Tangerines
Apples – Royal Gala ………… Oranges – Clementines
Apples – Granny Smith ….. Bananas

Better yet, how can we get categories and subcategories, so it looks like:
Apples
— MacIntosh
— Royal Gala
— Granny Smith
Oranges
— Tangerines
— Clementines
Bananas

or (better):
Apples ………………… Oranges
— MacIntosh ………. — Tangerines
— Royal Gala ………. — Clementines
— Granny Smith ….. Bananas

I tried to find solutions. These sound relevant but aren’t:
