# Conditional fields (Liquid templates)

## Overview

This article uses the current Opensense template syntax, Liquid (**as of 2022**). If you're used to the older format, see [Conditional fields (legacy templates)](https://help.opensense.com/docs/conditional-fields-pre-2022-legacy).

- You can make any field a conditional field.
- Make a field optional if some employees use it and some don't. It's removed automatically from the final email signature for employees who don't use it.
- You can wrap IF statements around any signature element, to make it appear **only** if that field is used: `{% if field %} {{field}} {% endif %}`.


## A conditional field on its own line

**HTML code view.** The row is wrapped in an if statement:

**Recipient's view.** If either field is removed, the separator line is removed too.

## Conditional fields that share a line

**HTML code view.** Each field has its own if block, and a nested condition shows the separator only when both fields have values:

**Signature preview with logic:**

**Recipient's view.** If either field is removed, the separator line is removed too.

<img src="https://help.opensense.com/media/conditionalfields5-66eba5bce737.png" alt="A rendered line with a phone number and a mobile number separated by a vertical bar" width="427" height="43" loading="lazy" decoding="async">

## "Not if" logic

Need "not if" logic? We have that too. Wrap your HTML with `{% unless field %} Alternative Text {% endunless %}` instead.

For example: `{% unless phone %} 1-800-MAINLINE {% endunless %}`
