- new project-neutral extension evo_megamenu_json (Evomedien): a Megamenu plugin holding entries, columns, items, teaser cards and a featured slot as nested records; presentation settings travel with the payload so the front end reads behaviour instead of hard-coding it; published as page.10.fields.megaMenu, driven by the site settings megamenu.contentUid and megamenu.storagePid - vitec:seed-megamenu fills one element from the live structure: 5 entries, 26 columns, 95 items, 4 story cards; items without a page yet are flagged pending so the front end falls back to the column link - vitec:debug-sets prints the resolved site set order - read-only diagnostics: check_megamenu_schema.php, check_typoscript_templates.php - docs: schema updates run via extension:setup (database:updateschema no longer exists in v14), and a JSON Accept header activates headless-mixed, which strips every set-added page field

|
|
*
|
|
* - as a field of the plugin's own content element (no configuration -
|
|
* the element renders itself),
|
|
* - as a page-level field for the site header, configured with either
|
|
* `contentUid` (a specific plugin element) or `storagePid` (the first
|
|
* megamenu element found on that folder).
|
|
*
|
|
* TYPO3 v14 hands the ContentObjectRenderer in through the setter rather
|
|
* than the constructor; without it $this->cObj stays null and the element
|
|
* path cannot see which record it is rendering.
