The Sorting enchantment is an enchantment that goes up to three levels, and can only be applied to leggings (since it’s akin to having pockets). While wearing leggings enchanted with Sorting, items that only stack up to a limited amount such as Ender Pearls or eggs can be stacked higher.

I: 4 extra items per stack (20 total)

II: 8 extra items per stack (24 total)

III: 16 extra items per stack (32 total)

This enchantment does not work for unstackable items like tools or filled buckets, it doesn’t allow for more items inside a bundle, and if the armor granting the enchantment is broken or destroyed, the “extra” items are sorted into their own stacks or dropped depending on inventory space.
