# Create a Custom Tab

Creating or configuring a custom tab, is done through JSON from either a Resource or Data pack. For this explanation, we will be using a resource pack.

When making changes to the resource or data pack, you will need to restart the game in order to view those changes. This is due to the way the tabs are created!

You can define multiple tabs inside a single pack. You do not need to create a custom one for each one

# Getting Started

The first thing you want to do is, create a new, empty resource pack. To save you some time, you can also download the SKELETON PACK with all the base files already created.

Inside your resource pack, you will need the following folder layout:

|-- Pack Folder
    |-- assets
        |-- minecraft
            |-- lang
                |-- en_us.json
            |-- morecreativetabs
                |-- my_tab.json
    |-- pack.mcmeta

When using the SKELETON PACK, these files/folders will already be created for you

# Creating your first tab

To create a new creative tab, create a file inside the morecreativetabs folder. You can call this whateveryouwant.json. This file will tell the mod how to configure the creative tab.

You will also need a lang file inside the lang folder. For this example, we will use en_us.json which is the english version of the tab names.

Below is a sample config file, with an explanation at the bottom:

{
  "tab_enabled": true,
  "tab_name": "lighting",
  "tab_icon": "minecraft:lantern",
  "tab_items": [
    {
      "name": "minecraft:light",
      "hide_old_tab": true,
      "nbt": "{BlockStateTag: {level:\"4\"}}"
    },
    {
      "name": "minecraft:torch"
    },
	{
      "name": "minecraft:soul_torch"
    },
	{
      "name": "minecraft:candle"
    }
  ]
}

Explanation:

Item/Variable	Purpose
"tab_enabled"	Should this custom tab be loaded by the mod
"tab_name"	The translation key used in the `lang` file. For example: `lighting_tab`. This will be prefixed with `morecreativetabs.` So `lighting_tab` will become `morecreativetabs.lighting_tab`
"tab_icon"	The registry name of the item to use as the tab icon. This must always be in format `modid:itemname`. You can find this by dropping an item on the ground and looking at it, with F3 active

"tab_items"	This contains a reference to all the items contained in the tab
"name"	The registry name of the item to use as the tab icon. This must always be in format `modid:itemname`. You can find this by dropping an item on the ground and looking at it, with F3 active
"hide_old_tab" -> Optional	When present and enabled, the item will be removed from its original tab, and only be shown in the custom tab
"nbt" -> Optional	Pretty self explanatory, but this allows you to set NBT values on an item inside the tab

"tab_enabled", "tab_name", "tab_icon" and "tab_items" must always be present, or the file will not load
