# Custom Item Templates

Custom item templates allow users to quickly create metadata items that adhere to a predefined, customisable template. These templates allow for changes that differ from the default Aristotle Metadata Registry page format (including the addition of [sub-pages](/administrator-tasks/custom-item-templates/creating-and-editing-custom-item-templates/creating-and-editing-item-template-sub-pages.md)), as well as custom item editors for the metadata items that use them.

### Custom item template functionality

{% hint style="info" %}
Only Registry Administrators can create and edit custom item templates.
{% endhint %}

Custom item templates can be:

* [Created and edited](/administrator-tasks/custom-item-templates/creating-and-editing-custom-item-templates.md)
* Used to [create templated metadata items](/administrator-tasks/custom-item-templates/creating-metadata-items-using-custom-item-templates.md)
* [Applied to or unlinked from existing metadata items](/administrator-tasks/custom-item-templates/removing-or-applying-an-item-template-for-an-existing-metadata-item.md).

**Note:** Sub-pages can only be added to a custom item template **after** its creation via editing the custom item template.
