Java Creative Menu should nest similar items/blocks (Similar to Bedrock)

This nested grouping menu would mean that all swords (This also applies to everything in Bedrock, blocks variants, types) would be grouped within 1 space and you click (+) to expand it to show all 5 swords and the (-) again to contract it to be smaller. This way it saves more space and allows for more items to be added without cluttering the Creative menu more.

Provided a graphic below of Bedrock's nested menu's to give an example of how Java's creative menu could declutter even more to fit more items; this is especially useful for the copper family of blocks which takes up a large amount of space which could fit in 1 slot to expand with 1 click with nesting.
