Hide removed an owner field from the schema, show and save, but a hidden
relation-manager field's relation routes (panel, link, unlink, child CRUD,
deferred commit) and a hidden partial field's partial stayed reachable.
dropHiddenFields now drops the relation and the partial path too; a partial
the list or preview header or another field still uses keeps rendering.
- admin-controllers: placement, values, Load/Save, permissions,
widgets, partials and boot errors, with the ExtrasPlugin snippet
- Example_formExtension compiles an owner form with the extension
- coming-from-wintercms maps extendFormFields, addFields, addTabFields
and removeField to the form extension
- cabana README feature bullet and Activate row
- placement: tabs before/after tab anchors, anchor cursor for plugin
order, own-field anchors sorted with cycle detection, Requires() rule,
anchor tab inheritance, Hide with reference checks, zone refusal (D-101)
- boot errors name plugin, controller and offending name; fileupload is
refused (D-100); localized tab label collisions checked in Activate
- extension widgets dispatch to AdminFormExtension.Actions, partials
render from the contributor's Dir through PartialData, plugin field
types decode for Save and load after Load, translatable values reach
Save as locale maps and never the owner's translations
- Permissions and Visible apply to schema, show, save, widgets and
partials; AdminFormErrors answer 422, Save notices join meta.notices
