On the [heaviest sats board](https://blockspace.wiki/glossary/heaviest-sats-board/), a sub-item tab shows the sats among the 100,000 that carry one kind of content: Ordinal Inscriptions, BRC-20 inscriptions, bitmaps, sat names or CAT-21 sats. A sub-item is named in words and wears its family's colour, so every row stays the Ordinal Sats colour. Each tab shows how many sats it holds.
