Item Group Creator
Item Group Creator is a Fabric mod designed to allow, through JSON files within the mod's own resources, both on the client and server side, the addition of new sections in the creative inventory.
What can you do?
- Create new inventory groups with custom names and icons.
- Include items from any mod.
- Include base Minecraft items.
- Configure specific NBTs for items.
These sections are fully configurable and support NBTs and items from other mods, allowing you to organize all your content.
Important version note
Be careful with Minecraft versions:
In 1.21.1, item components use square brackets [...]
In 1.20.4 and below, items use classic NBT {...}
Note: Each example below is already adapted to its correct version. Make sure you use the correct format for your server/version, otherwise items may not work or groups may fail to load.
Configuration path
To create your own groups, place the JSON files in the following path:
data/itemgroupcreator/groups/
Note: The inner folder
/groupsis where the mod looks for the different item JSON files when starting the game or server.
