The anatomy of a Sector add-on

We are updating our documentation library to be ready for the Sector 10! Find out more in our Sector 10 roadmap or head straight to our collection of Sector 10 - Changes and Updates.

Sector Add-ons

Each element in the Sector Ecosystem follows the same principle - once installed, your editorial team is ready to go. To make this happen, each Sector add-on comes with a set of tools. Some are as you would expect, while some go further.

What makes a Sector add-on a Sector add-on?

Using a consistent approach to the Drupal configuration, add-ons might need to use install hooks back to the Starter Kit, but all Sector components need to deliver more. This includes:

  • Useful and usable sample content 
  • Testplans and code review
  • Online demo 
  • Documentation on
  • Project pages on
  • GitHub repository and composer

So - what does this look like in real life?

Drupal configuration

Each add-on includes a set of preconfigured components. The configuration can include:

  • Content types and preconfigured displays - at a minimum, view modes for default, short teaser, and teaser (all displays are configured to work across automated listings across a Sector site)
  • Consistent content type settings and configured AdminUI form displays to keep everything uniform for editors
  • Consistent view settings and preconfigured view displays - for most content types this includes a page, a teaser block using the teaser view modes, and a short teaser block using the short teaser view modes. 
  • Taxonomies with consistent settings - including descriptions and rabbit hole settings.
  • Drupal blocks if and where required.

For an example of preconfigured components for an add-on, see the Sector Blog documentation.

Hooks into the Starter Kit 

The add-on might also require a few install hooks back into the Starter Kit. These might include:

  • User permission to hook into the preconfigured user roles in the Starter Kit - or a specific user role if the use case supports this. 
  • XML sitemap setting (yeah ... we are working on this). 
  • You can also hook into search settings, e.g if you want your content to be indexed by default. 

Useful and usable sample content 

The sample content allows the editorial team to see at one glance how the new feature works.  

  • Sample content is informative and links back to documentation. 
  • Includes the words { sample content }, to be easily found and deleted prior to the site going live.  

For an example, see sample content for Sector Index on the Sector demo.

Testplans and code review

Each Sector add-on has a testplan following the Sector testplan template (coming soon!) and is peer reviewed. Automated tests are a work in progress (they always are).

Online demo

Each add-on is installed on the official Sector demo site - this is the best way to see if everything integrates seamlessly!

Documentation on 

Documentation is an important part of the Sector Ecosystem. Each Sector add-on has one or more documentation pages on The mandatory sitebuilder documentation is aimed at sitebuilders - listing all related entities and links to configuration screens (see the Sector Blog documentation page for an example of what is included).

We are also aiming to have a content editor's guide for each add-on - for example, Editing a resource

Project page on

The official home for each Sector add-on is a project page on (like the Drupal page for the Sector Blog ) and each add-on is linked from the Drupal Sector project page. 

GitHub repository and composer

Each add-on can be installed via composer. See the Sector Ecosystem for more.
