• Minecraft 1.21, 1.21.1, 1.21.11, 26.1.2, and 26.2: Ingredients and Visibility

Overview

JEI automatically adds items from the following sources:

1. Creative Tabs
2. Item Registry
3. Block Registry (using Item.getItemFromBlock(block))

Adding Items

• If you want to add items to JEI, just make sure they are registered with the game correctly.

• If a subtype of your item is missing, make sure it is in your mod's creative tabs.

• If it's in the creative tab but still missing, JEI probably thinks the item is a duplicate of a similar item.
  To resolve this issue see the section on Item Subtypes.

Removing Items

See the section on Hiding Ingredients.

See ItemStackListFactory for the implementation.
