# Deprecated Features

{% hint style="danger" %}
Do not use this features! They are there for original MoreCreativeTabs resource packs compatibility
{% endhint %}

| Deprecated feature | Purpose                                                                                                        |
| ------------------ | -------------------------------------------------------------------------------------------------------------- |
| "replace"          | Uses filename-based replacement when `tab_replace` is not present.                                             |
| "hide\_old\_tab"   | When present and enabled, the item will be removed from its original tab, and only be shown in the custom tab. |

Instead of using "hide\_old\_tabs" you can just replace the old tab and remove item you don't want.

Example:

```json
{
  "tab_enabled": true,
  "tab_replace": "itemgroup.building_blocks",
  "tab_items": [
    {
      "name": "existing", "except": ["minecraft:oak_log", "minecraft:birch_log"]
    }
  ]
}
```
