How do I add a user defined field to customize catalog registration?
When creating or managing a catalog as a Catalog admin, you can create custom user defined fields. These fields allow you to customize your user registration beyond the default fields of Full Name and Email. Information in user defined fields can only be collected as part of new user registrations; the fields do not display when existing users enroll in a course.
Any user defined fields in the parent catalog can automatically apply to subcatalogs. However, you can choose to create your own custom user defined fields for a subcatalog.
Note: In subcatalogs, you cannot add a new field if the subcatalog is inheriting user defined fields from another catalog.
Add Field

Click the Add Field button.

Choose HTML Input Type

In the HTML Input Type menu, select whether you want to create a text or checkbox field.
Create Name and Label

In the Name field [1], create the name for the field. Spaces are not allowed; you must use underscores or dashes between words.
In the Label field [2], enter the text for the field that users will see during registration.
If the field is required to be completed by users, click the This field is required checkbox [3].
