create-form-tab-layout

Development

Create a multi-tab form layout using PrestaShop's NavigationTabType. This is a specific pattern for complex forms with many fields organized by tabs — NOT the default form layout. Most forms do not need tabs. Trigger: "create tab layout for {Domain} form", "add tabs to {Domain} form".

create-form-tab-layout

This is NOT the default form pattern. Most entity forms are simple single-page forms using TranslatorAwareType or AbstractType. Only use NavigationTabType when the entity has many fields that benefit from tab organization (e.g. Carrier with general, shipping, size/weight tabs).

Instructions

In root {Domain}Type, declare NavigationTabType as the parent type via getParent():
```
public function getParent(): string
{
    return NavigationTabType::class;
}
```
Then in buildForm(), add each tab as a sub-form — each child is rendered as a tab.
Create one form type per tab: {Domain}GeneralTabType.php, {Domain}ShippingTabType.php, etc.
Each tab type extends TranslatorAwareType with its own buildForm() containing only that tab's fields.
Tab anchor IDs (used for JS error scrolling) are derived from the tab names.

Rules

Conventions (NavigationTabType is PS-specific, tab anchor IDs for JS error nav) are in Forms/CONTEXT.md. Skill-specific reminders:

Each tab gets its own form type class for maintainability
Tab titles must use $this->trans() for translation
