# Registration Fields

Custom registration fields collect extra user data during account creation and can be scoped to stores and categories.

Create custom fields

1. Go to the registration fields configuration (plugin area).
2. Add a field (text, dropdown, checkbox, etc.) and provide a key that maps to a NexPort Campus custom profile field.
3. Optionally scope the field to specific stores or categories.

Dropdown behavior

* Provide a default option like “Please choose” for clarity.
* Option values display in alphabetical order.

Store scoping and cloning

* Clone existing fields to reuse options with different store/category scoping.

Validation examples

* Library stores can validate library card formats using regex. Configure a helpful validation message for failed entries.
