Create and edit

Status: ✅ Implemented (as patterns over AutoCrud)

Intent

Let users create and edit records with the right amount of ceremony: a plain form for simple entities, a rich multi-section page for complex ones, or a drawer that slides over the listing for quick edits.

Simple: routed forms

AutoCrud<T> gives the Redwood Create and Edit — Simple template out of the box: /new and /{id}/edit routed forms with validation, optimistic locking and the dirty guard. No extra code.

Advanced: sections, zones and tabs

The Redwood Create and Edit — Advanced template is the same edit form composed for a complex record: grouped sections, multi-column zones and tabbed areas. In Mateu that is a composition of the existing layout vocabulary on the entity’s edit form, not a separate archetype:

• @Section(name, columns) on entity fields groups the form into titled sections (add propertyList = true for read-only label/value rows).
• @Zones + @Section(zone = ...) arranges sections in side-by-side zones (e.g. main content left, summary/audit right).
• Tabs — a @Panel-grouped tab layout or a TabLayout in a custom form component for “Details / History / Attachments” areas.
• @ReadOnly, @Help, @Stereotype fine-tune per-field behavior; bean-validation annotations drive validation.

All of it renders with the same anatomy (page header, color strip, footer actions) on every renderer — see the demo classes in demo/demo-admin-panel for live examples and the forms guide for the full field/layout vocabulary.

Drawer: edit over the listing

editInDrawer() on the crud switches New/Edit to the Create and Edit — Drawer template: the form slides over the listing, which never unmounts; saving persists, closes the drawer and re-runs the search in place. See Drawer and the /drawer-crud-demo showcase page.

When to use what

• Few fields, fast data entry → Simple (default AutoCrud).
• Rich record with grouped content → Advanced (@Section/@Zones/tabs on the same crud).
• Quick edits where context matters → Drawer (editInDrawer()).
