# Customize the Sequence Number on Waitlist Participant Cards

Use a custom field on the waitlist participant object to replace the system-generated 1, 2, 3 prefix on waitlist participant cards. Lobby Management renders whatever value the mapped field contains, so your business logic decides what each card shows.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: Lightning Experience.</td></tr><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: <strong>Enterprise</strong> and <strong>Unlimited</strong> Editions</td></tr></tbody></table>

By default, Lobby Management shows a system-generated index — 1., 2., 3. — in each waitlist participant card header. When you map a custom field on the waitlist participant object, Lobby Management replaces the index with the field’s value.

## Plan Your Custom Field

Plan how Lobby Management reads your custom field:

- Lobby Management displays whatever value your custom field contains. Implement backend logic, typically an Apex trigger on the waitlist participant record, to calculate the position you want shown and write it to the custom field. For information about writing triggers, see [Apex Triggers](https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_triggers.htm).
- To create a custom field on the waitlist participant object, see [Add Custom Fields](https://help.salesforce.com/s/articleView?id=platform.adding_fields.htm&type=5&language=en_US). Ensure that the field is of the type **Text** or **Number**.

## Reorder Participants

By default, Lobby Management doesn't sort or position participants on the waitlist based on the mapping. Move a participant on the waitlist from a trigger or Apex class. Use the Waitlist Participants Connect API from your trigger or Apex class to move a participant to a specific position, the top, or the bottom of the waitlist.
