Custom Sulu Template Development
A client recently approached us with a task: a service page needed to contain blocks for “Text,” “Image+Text,” “Call to Action,” and a sidebar with a feedback form. Sulu’s standard templates didn’t offer that combination—they would have had to hack the admin interface or create a custom template. We built the solution in 2 days: an XML schema with the required block types, a Twig template for rendering, and a custom controller to load testimonials. Now the manager can assemble the page from ready-made blocks in minutes. Our team has 5+ years of experience with Sulu CMS and has delivered 20+ projects, ensuring bug-free, requirement-compliant output. This flexibility lets our clients save up to 30% on maintenance budgets by eliminating hacks. When developing 5–8 custom templates for a corporate site, savings can reach 40% compared to purchasing a ready-made solution.
Why a Custom Sulu Template Is Better Than a Standard One
Standard templates cover basic needs. But for unique pages, you often need fields that aren’t in the box. A custom template allows:
- Add any field types: text editors, media, blocks with arbitrary structure.
- Create multiple layouts for the same page type.
- Connect a custom controller to load additional data (e.g., related records or testimonials).
- Control the view through Twig templates without limitations.
The result is flexibility impossible with standard solutions, with maintenance cost reduction of 30–50% thanks to eliminating workarounds. According to Sulu documentation, custom controllers save time on integrations.
How to Develop a Custom Sulu Template
The process includes several stages:
- Analyze page requirements and agree on structure.
- Design an XML schema with fields and blocks.
- Develop a Twig template with the design in mind.
- Write a custom controller (if additional data is needed).
- Integrate with the existing theme and test.
- Deploy to the server and final verification.
- Provide documentation and training.
Timelines depend on complexity. Below are approximate durations for different template types.
| Template Type | Unique Blocks | Development Time |
|---|---|---|
| Simple (text, media) | 2–4 | 1–2 days |
| Medium (block editor, custom fields) | 5–8 | 2–3 days |
| Complex (custom controller, integrations) | 8+ | 3–5 days |
Comparison of Standard and Custom Template
| Criterion | Standard Template | Custom Template |
|---|---|---|
| Number of fields | Limited | Unlimited |
| Block types | Only text | Text, media, CTA, gallery, etc. |
| Controller | Only DefaultController | Custom with any logic |
| Flexibility | Low | High |

class ServiceController extends AbstractController { public function indexAction(StructureInterface $structure): Response { $testimonials = $this->testimonials->findByService($structure->getUuid(), limit: 3); return $this->render('pages/service.html.twig', [ 'content' => $structure->getContent(), 'testimonials' => $testimonials, ]); } } Registering the Template in Webspace
<templates> <template type="page">service</template> </templates> After adding the template, clear cache and reindex:
php bin/console cache:clear php bin/console sulu:document:initialize Typical Pitfalls and Solutions
- Template not applied — most often forgotten to register the key in webspace or clear cache. Always check the config entry and run
cache:clear. - Incorrect controller reference — specify the full class and method, otherwise Sulu won't find the controller. Use
debug:routerto verify. - Blocks not displayed — ensure that in the Twig template, each block type has corresponding logic. A common mistake is missing the
typecheck in the loop.
