Help Center templating cookbook (Guide Professional and Enterprise)

Each Help Center theme consists of a collection of editable page templates. You can use the Help Center templating language, Curlybars, to access Help Center data and manipulate the content in your pages.

This article provides a list of recipes with code snippets you can use. Keep in mind that, some of the functionality in these recipes might already be in your Help Center, depending on whether you are using a standard theme or a customized theme and the date you enabled your Help Center.

Access to the page code is available on Guide Professional and Enterpise.

Note: Trial users are given the Guide Professional plan, which includes code editing options, but they can no longer access that feature if they do not purchase Guide Professional or Enterprise.

About the Curlybars templating language

Help Center is built on a theming framework that includes its own templating language for advanced customizations.

Each Help Center theme consists of a collection of  editable page templates that define the layout of different types of pages in Help Center. For example, there's a template for knowledge base articles, a template for the list of requests, and so on. A template is simply a text file to be rendered into an HTML page when a user wants to see it. Each template consists of a mix of HTML markup and expressions identifiable by double curly brackets such as {{post.title}}.

The templating language is named Curlybars and implements a large subset of the Handlebars language. But unlike Handlebars which renders on the client-side, Curlybars renders on the server-side.

You can use the Help Center templating language to access Help Center data and manipulate the content in your pages. In the following example, Help Center renders a list of names and avatars of all the people who left comments on the page:

{{#each comments}}
  <li>
    <div class="comment-avatar">
      <img src="{{author.avatar_url}}" alt="Avatar" />
    </div>
    <div class="comment-author">
      {{author.name}}
    </div>
  </li>
{{/each}} 

Previously you could use components to customize Help Center, but you could not customize the components themselves, except for manipulating them with Javascript. With Curlybars you can get access to the HTML that was previously hidden inside component and edit it.

    Sort by: 
    {{#each comment_sorters}}
      <a aria-selected="{{selected}}" href="{{url}}">{{name}}</a>
    {{/each}}
