# Duplicate Field

This document explains how to add and configure the Duplicate field in a template, including duplication rules inside tables.

Use **Duplicate field** to show the value of another field in a second place.

The duplicate is read-only. It mirrors the parent field value.

You can place this field in:

* structured documents
* PDF documents

{% hint style="warning" %}
You can’t remove the parent field while at least one duplicate exists.
{% endhint %}
