原文外掛簡介
Beplus Visual Mega Navigation adds a Gutenberg-powered mega menu builder to Appearance → Menus. A top-level (depth-0) menu item can get a visual panel designed with the block editor instead of a plain sub-menu, and the panel is rendered on the front end by a menu walker that keeps keyboard and screen-reader behaviour intact.
Features
Visual builder — design panel content with the block editor: columns, headings, images, buttons, lists, and the plugin’s navigation blocks.
Per-item settings — enable or disable the panel, panel width, custom width, panel position, and open animation for each top-level menu item.
Starter templates — apply a ready-made layout from the template store, import a JSON file, or export the current design.
Block patterns — the BePlus Header Inline — Logo / Menu / Toggle pattern is available in the Site Editor for block themes.
Root-level only — only top-level menu items can host a mega panel.
Accessible front end — the front-end script manages aria-haspopup, aria-expanded, and aria-controls; Escape closes an open panel and moving focus out of the panel closes it.
Theme friendly — panel markup uses beplus-vmn-* classes and --beplus-vmn-mega-* CSS custom properties, and the width mode is exposed as has-mega-menu--{width} on the menu item.
Nothing extra in the database — settings and content are stored in nav_menu_item post meta, and the legacy _jemented_megamenu_* keys are still read on migrated sites.
Requirements
WordPress 6.0 or higher.
PHP 8.0 or higher.
WooCommerce — optional, required by the Product List and Product Card blocks.
Node.js — development builds only; the required version is pinned in .nvmrc (currently 24).
Getting started
Go to Appearance → Menus and open (or create) a menu.
Click Mega Menu on a top-level menu item. The Mega Menu Builder opens for that item only.
On the Settings tab, turn on Enable Mega Menu and choose the panel width, position, and open animation.
Switch to the Content Builder tab and build the panel with the block editor.
Use Import or Export in the modal header to apply a starter template or download the current design as JSON.
Click Save.
Mega menu templates
Templates are JSON files discovered from these locations. When the same slug exists in more than one place, the last location wins.
Plugin — beplus-visual-mega-nav/templates/*.json (lowest priority).
Parent theme — {theme}/mega-menu-templates/*.json.
Child theme — {child-theme}/mega-menu-templates/*.json (highest priority).
Built-in templates:
featured-with-links — Featured + Links.
mega-4-columns — 4 Columns.
blog-and-quote-2-cols — Quotes + blog list.
hero-artwork-3-cols — Hero Artwork 3 cols.
A theme file with the same slug as a plugin template replaces the plugin version in the Import dropdown. Exported files use the same format, so you can drop an export into mega-menu-templates/ and add a slug to publish it in the store.
Template file format
Each template is a single JSON object:
{
"slug": "my-custom-menu",
"title": "My Custom Menu",
"description": "Optional short description shown in the Import dropdown.",
"version": "1.0.0",
"settings": {
"width": "full",
"customWidth": 1200,
"position": "item-left",
"bgColor": "",
"animation": "fade"
},
"content": "Serialized block markup"
}
Fields:
slug — used as the filename ({slug}.json); falls back to the filename without .json.
title — label shown in the Import dropdown.
description — optional text shown under the title.
version — template metadata only.
settings — optional panel settings applied with the template.
content — required, serialized block markup in the same format that is saved to the menu item.
Panel settings keys:
width — full or custom.
customWidth — panel width in pixels when width is custom (200–2400, default 780).
position — item-left, item-center, or screen-center (used with a custom width).
bgColor — panel background color as a hex value.
animation — fade, slide, or none.
Template content is sanitized on load with the same rules as saved mega menu content, so only blocks from the allowed list below are kept.
Included blocks
Core blocks available in the Content Builder: Columns, Column, Group, Row, Stack, Heading, Paragraph, List, List item, Image, Buttons, Button, Separator, Spacer, Cover, Page List, Shortcode, and Custom HTML.
Blocks added by this plugin:
Menu List and Menu Item — navigation lists with current-page detection, active state styling, and badges.
Link Item — single navigation link with an optional description and badge.
Tab Container and Tab Panel — tabbed mega menu content, vertical sidebar or horizontal top bar.
BePlus Header and BePlus Navigation — header container with sticky and scroll effects, plus a classic menu with hamburger toggle.
Menu Area — renders a classic WordPress menu inside the panel using the mega menu engine.
Nav Toggle — hamburger button that opens the mobile navigation overlay.
Hero Artwork Dock, Blog List, Quote, Product List, and Product Card — content blocks for promotional panels.
Third-party blocks appear in the Content Builder once they are registered, and you can allow them with the beplus_vmn_allowed_blocks filter.
REST API
The admin screen uses these routes. All of them require the edit_theme_options capability.
GET /wp-json/beplus-visual-mega-nav/v1/item/{id} — read enabled, settings, and content for a menu item.
POST /wp-json/beplus-visual-mega-nav/v1/item/{id} — save enabled, settings, and content.
GET /wp-json/beplus-visual-mega-nav/v1/templates — list template summaries (slug, title, description, source).
GET /wp-json/beplus-visual-mega-nav/v1/templates/{slug} — load one template, including settings and content.
Developer hooks
Filters provided by the plugin:
beplus_vmn_locations — theme locations that use the mega menu walker (default primary, main-menu, header).
beplus_vmn_apply_walker — force the walker on or off for a given wp_nav_menu() call; return true or false.
beplus_vmn_allowed_blocks — block names allowed in the Content Builder.
beplus_vmn_template_directories — template scan directories, keyed by source label.
beplus_vmn_templates — template list returned to the admin UI, keyed by slug.
beplus_vmn_template_data — a single template before it is returned by the REST API.
beplus_vmn_template_part_content — markup of a bundled block pattern before it is registered.
beplus_vmn_link_item_attributes — Link Item block attributes before rendering.
beplus_vmn_link_item_render_markup — rendered Link Item HTML.
beplus_vmn_link_item_badge_variants — allowed badge variant slugs.
Example: adding a custom block to the Content Builder.
add_filter( 'beplus_vmn_allowed_blocks', function ( array $blocks ): array {
$blocks[] = 'my-plugin/featured-card';
return $blocks;
} );
Example: adding a template directory.
add_filter( 'beplus_vmn_template_directories', function ( array $directories ): array {
$directories['my-plugin'] = plugin_dir_path( __FILE__ ) . 'mega-menu-templates';
return $directories;
} );
Data storage
Each menu item stores three meta values on the nav_menu_item post:
_beplus_vmn_enabled — whether the item renders a mega panel.
_beplus_vmn_settings — JSON string with the panel settings listed above.
_beplus_vmn_content — serialized block markup.
Development
npm run start — watch admin assets.
npm run build — production build into build/.
composer check — PHP lint, PHPCS, PHPStan.
npm run check:js — ESLint and Stylelint.
