7 Steps to Create a New Admin Menu in Magento 2

Have you ever questioned how far you can customize the admin menu in Magento 2?

Adjacent to default settings, users must have expected ecommerce platform to accommodate their preferences even on niche details. The prevailing platform that won the game should be the one with the highest customization to target a large range of contrasting usage purposes. Magento genuinely understands that and gives many rooms to tailor the admin menu.

Let’s get into steps to find out how to create a new module that displays a simple page in the Magento admin.

Step 1: Register the module. Create the file registration.php

Path:  app/code/Bss/CreateMenuBackend/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
   \Magento\Framework\Component\ComponentRegistrar::MODULE,
   'Bss_CreateMenuBackend',
   __DIR__
);

Step 2: Configure module. Create file module.xml

Path:  app/code/Bss/CreateMenuBackend/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
   <module name="Bss_CreateMenuBackend" setup_version="1.0.0">
   </module>
</config>

Step 3: Create file menu.xml

Path:  app/code/Bss/CreateMenuBackend/etc/adminhtml/menu.xml

– Below is a sample of main menu, set name as: “Bss Menu”.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
   <menu>
       <add id="Bss_CreateMenuBackend::menu"
           title="Bss Menu" module="Bss_CreateMenuBackend"
           sortOrder="10"
           resource="Magento_Backend::content"
           />
   </menu>
</config>

Attributes:

• Id: Specify identifier of the menu. It should be unique and comply with the format: [Namespace_ModuleName]::[menu_name].
• Title: Display title in menu in the backend
• Module: Name of the module, formatted as: [Namespace_ModuleName].

• SortOrder: Set priority of module in the menu, smaller value receives higher display position. Module receives value “0” can be added with an icon.
• Resource: Create ACL rule to set admin users who can see and access the created menu

–  Enter following commands in root file of Magento:

1: php bin/magento module:enable Bss_DemoMenu
2: php bin/magento setup:upgrade
3: php bin/magento setup:static-content:deploy -f
4: php bin/magento cache:flush

It turns out a main menu Bss Menu at the left navigation – Admin Menu

– Create a new sub-menu in the main menu. Set Bss Items as its name.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
   <menu>
       <add id="Bss_CreateMenuBackend::menu"
           title="Bss Menu" module="Bss_CreateMenuBackend"
           sortOrder="10"
           resource="Magento_Backend::content"
           />
       <!-- START: new node -->  
       <add id="Bss_CreateMenuBackend::menu_item"
           title="Bss Items" module="Bss_CreateMenuBackend"
           sortOrder="10" parent="Bss_CreateMenuBackend::menu"
           action="createmenubackend/create/index"
           resource="Bss_CreateMenuBackend::menu_item"
           />
       <!-- END:   new node -->
   </menu>
</config>

Attributes in sub-menu:

• Parent: Value is the ID of the main menu. It specifies the sub menu belongs to parentory menu.
• Action: Direct URL if clicking to the menu, as format [router_name]/[controller_name]/[action_name]. – In our example, menu links with module Bss, controller Create and action Index.

Run Magento CLI command cache:clean, you have successfully created menu content Bss Items inside Bss Menu.

Step 4: Create file routes.xml

Path:  app/code/Bss/CreateMenuBackend/etc/adminhtml/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="admin">
<route id="createmenubackend" frontName="createmenubackend">
<module name="Bss_CreateMenuBackend"/>
</route>
</router>
</config>

Step 5: Create page to attach link in the menu. Create file Index.php

Path:  app/code/Bss/CreateMenuBackend/Controller/Adminhtml/Create/Index.php

<?php
namespace Bss\CreateMenuBackend\Controller\Adminhtml\Create;
class Index extends \Magento\Backend\App\Action
{
         protected $resultPageFactory = false;      
         public function __construct(
                 \Magento\Backend\App\Action\Context $context,
                 \Magento\Framework\View\Result\PageFactory $resultPageFactory
         ) {
                 parent::__construct($context);
                 $this->resultPageFactory = $resultPageFactory;
         } 
         public function execute()
         {
                 $resultPage = $this->resultPageFactory->create();
                 $resultPage->setActiveMenu('Bss_CreateMenuBackend::menu');
                 $resultPage->getConfig()->getTitle()->prepend(__('Demo Menu'));
                 return $resultPage;
         }
         protected function _isAllowed()
         {
                 return $this->_authorization->isAllowed('Bss_CreateMenuBackend::menu');
         }
}

Step 6: Determine the interface of the page

Define layout and page structure. Create file createmenubackend_create_index

Path: app/code/Bss/CreateMenuBackend/view/adminhtml/layout/createmenubackend_create_index.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
   <body>
       <referenceContainer name="content">
               <block class="Magento\Backend\Block\Template" template="Bss_CreateMenuBackend::helloworld.phtml"/>
       </referenceContainer>
   </body>
</page>

Set up page content. Create file helloworld.phtm

Path: app/code/Bss/CreateMenuBackend/view/adminhtml/templates/helloworld.phtml

<p>Hello World</p>

Step 7: Install module

Run command in root file of Magento:

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

This is the outcome when clicking to sub-menu Bss Items:
