# Adding custom fields

{% hint style="info" %}
Custom fields can only be added by an Administrator.
{% endhint %}

Custom fields allow you to add a new, **registry-wide** field to metadata items that aren't included in the ISO 11179 standard.

### How to add a custom field <a href="#how_to_add_a_custom_field" id="how_to_add_a_custom_field"></a>

1. Select 'Administrator tools' from your Dashboard side panel, then 'Manage Custom Fields'.

2. **If you wish to add a custom field usable by all metadata item types,** select 'Edit' from the '*All*' row. **If you wish to add a custom field usable only by a single metadata item type*****,*** select 'Edit' from the row matching the desired metadata item type.

**Note:** Upon creation, custom fields will not be searchable. A [reindex task](/administrator-tasks/task-runner/resolving-issues-with-search-using-reindex.md) must be completed in order to search for a metadata item by its custom field(s).
