Handlebar Helper Function: Unless
Conditionally renders a block based on whether a value evaluates to false. This behavior is the inverse of the if helper.
This built-in helper is provided by the Handlebars.Net library.
This helper is available in the Winter ’26 release of Marketing Cloud Next (API version 65.0).
| Parameter | Type | Description |
|---|---|---|
condition | Any | Required. The value to evaluate. |
The function renders the block template if the condition evaluates to false. If an {{else}} block is provided, it renders that block when the condition evaluates to true.
