FirstHandlebarsHelper (Terminalfour Handlebars Helpers (Version 8.3.15-HANDLEBARS-ALPHA))

java.lang.Object
- com.terminalfour.publish.handlebars.helper.BaseHelper
- - com.terminalfour.publish.handlebars.helper.content.FirstHandlebarsHelper

All Implemented Interfaces:

com.github.jknack.handlebars.Helper<Object>
```
@Component
public class FirstHandlebarsHelper
extends BaseHelper
```
The {{first}} handlebars helper is used to process the first content item in a section in a different way to the rest of the content items in the section.
In general this helper is used as a block level helper, but if used as an inline expression, it returns true for the first content item and false for others.

If there is no currently publishing content item, this helper returns false.

Usage
```
  {{#first}}
   <ul>
  {{/first}}
    <li>{{publish element="Name"}}</li>
  {{#last}}
   </ul>
  {{/last}}
 
```
In the above example, an opening ul is output for the first content item in the section and a closing ul is output for the last content item. This allows for all content items to be wrapped with specific code, in this case an unordered list.
