# Custom Item Categories

The Custom Item Categories is where the fun begins.

```ruby
CUSTOM_CATEGORY_NAMES = {
  "Evolution Stones" => { 
    :items => [:FIRESTONE, :THUNDERSTONE, :WATERSTONE, :LEAFSTONE, :MOONSTONE, :SUNSTONE, :DUSKSTONE, :DAWNSTONE, :SHINYSTONE, :ICESTONE],
    :order => 11
  },
  "Type Plates" => {
    :items => [:FLAMEPLATE, :SPLASHPLATE, :ZAPPLATE, :MEADOWPLATE, :ICICLEPLATE, :FISTPLATE, :TOXICPLATE, :EARTHPLATE, :SKYPLATE, :MINDPLATE, :INSECTPLATE, :STONEPLATE, :SPOOKYPLATE, :DRACOPLATE, :DREADPLATE, :IRONPLATE, :PIXIEPLATE],
    :order => 12
  },
  "Type Gems" => {
    :items => [:FIREGEM, :WATERGEM, :ELECTRICGEM, :GRASSGEM, :ICEGEM, :FIGHTINGGEM, :POISONGEM, :GROUNDGEM, :FLYINGGEM, :PSYCHICGEM, :BUGGEM, :ROCKGEM, :GHOSTGEM, :DRAGONGEM, :DARKGEM, :STEELGEM, :FAIRYGEM, :NORMALGEM],
    :order => 13
  }
}
```

I've provided some examples already. One of these example is **"Evolution Stones"** which is a hash that has a key named `:items` which is an array that contains all the Evolution Stone Items. You can also provide an `:order` key which will sort the Categories accordingly. 

The Default Category's `:order` is their pocket ID \* 10. If you added custom Pocket names to the bag, you can know the `:order` by doing the same calculation (Pocket ID \* 10).

* "Items" => order = 10
* "Medicine" => order = 20
* "Poké Balls" => order = 30
* "TMs & HMs" => order = 40
* "Berries => order = 50
* "Mail" => order = 60
* "Battle Items" => order = 70
* "Key Items" => order = 80

The Result in game will be as follow:

<div align="left"><figure><img src="/files/gRiauNRFknVDfMLnBW9k" alt="" width="375"><figcaption><p>Custom Item Categories</p></figcaption></figure></div>

Since we assigned 11 to `:order`, the **"Evolution Stones"** Category will be placed after the **"Items"** Category.&#x20;

But in this example there's no are no items that belong to the **"Items"** Category so the first Category shown is the **"Evolution Stones"** Category. The next Category will then be **"Type Plates"** and then **"Type Gems"** since they have an `:order` of 12 and 13 respectivily.&#x20;

The Category there after is **"Medicine"** if there are Items that belong to this Category.

In other words it just follows up the number of the `:order` assigned.

If you don't provide an `:order` then it'll be placed at the end by default.
