Customize the appearance of Express forms in Concrete CMS.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Customizing Express Form
The Express Form is a core block type in Concrete CMS. You can customize the appearance of Express Forms by creating custom templates and overriding the default form context.
## Creating a Form Context Class
To define custom template locations for Express Forms, start by creating a custom `FrontendFormContext` class. This class allows you to specify a custom attribute context.
```php
<?php
namespace Application\Express\Form\Context;
use Concrete\Core\Express\Form\Context\FrontendFormContext as CoreFrontendFormContext;
class FrontendFormContext extends CoreFrontendFormContext
{
public function getAttributeContext()
{
return new \Application\Attribute\Context\FrontendFormContext();
}
}
```
## Applying the Custom Form Context Class
To use your custom Form Context, you must create a custom `FormController` class and register it within the context registry.
```php
<?php
namespace Application\Express\Controller;
use Application\Express\Form\Context\FrontendFormContext;
use Concrete\Core\Express\Controller\StandardController;
use Concrete\Core\Express\Form\Context\FrontendFormContext as CoreFrontendFormContext;

How to install
mdr add macareuxdigital/concretecms-skills/customizing-express-form@sha256:312e3f6d3c8b79fcThe line at the top of this page pins the label git:20260913.db96265, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
