Overview

To show how to add custom ui grid to the admin panel, we will use MageDirect_Faq module from this article.

Create ACL

Create Access Control List Rules (ACL) file to control access to our Faq grid:

<!-- app/code/[VendorName]/[ModuleName]/etc/acl.xml -->

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Acl/etc/acl.xsd">
   <acl>
       <resources>
           <resource id="Magento_Backend::admin">
               <resource id="Magento_Backend::content">
                   <resource id="Magento_Backend::content_elements">
                       <resource id="MageDirect_Faq::faq" title="Faqs" translate="title" sortOrder="100"/>
                   </resource>
               </resource>
           </resource>
       </resources>
   </acl>
</config>

<?xml version="1.0"?>

<acl>

</resource>

</resources>

</acl>

</config>

Add new menu item

Add new menu item by editing etc/adminhtml/menu.xml inside the module. In this case, we will add an item under Content > Elements:

<!-- app/code/[VendorName]/[ModuleName]/etc/adminhtml/menu.xml -->

<?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="MageDirect_Faq::faqs" title="Faqs" translate="title" module="MageDirect_Faq" sortOrder="100" 
            parent="Magento_Backend::content_elements" action="faq/faq" resource="MageDirect_Faq::faq"/>
   </menu>
</config>

<?xml version="1.0"?>

<menu>

<add id="MageDirect_Faq::faqs" title="Faqs" translate="title" module="MageDirect_Faq" sortOrder="100"

parent="Magento_Backend::content_elements" action="faq/faq" resource="MageDirect_Faq::faq"/>

</menu>

</config>

“Add” directive has next attributes:

the id attribute is the unique name in format VendorName_ModuleName::menu_name;
the title attribute will be visible in the menu bar;
the module attribute specifies the module which this menu item belongs to;
the action attribute contains the url of the page on which our admin grid will be shown;
the resource attribute is used to define the ACL rule which the admin user must have in order to access this menu item;
the parent attribute defines parent menu item;
the sortOrder attribute defines menu item position inside menu bar.

Add routes.xml

To etc/adminhtml folder add routes.xml file with the next content:

<!-- app/code/[VendorName]/[ModuleName]/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="faq" frontName="faq">
           <module name="MageDirect_Faq" />
       </route>
   </router>
</config>

<?xml version="1.0"?>

</route>

</router>

</config>

Create admin controller class

<?php

// app/code/[VendorName]/[ModuleName]/Controller/Adminhtml/Faq/Index.php

namespace Magedirect\Faq\Controller\Adminhtml\Faq;

use Magento\Backend\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;

class Index extends \Magento\Backend\App\Action
{

    /**
     * Authorization level of a basic admin session
     *
     * @see _isAllowed()
     */
    const ADMIN_RESOURCE = 'MageDirect_Faq::faq';

    /**
     * @var PageFactory 
     */
    protected $resultPageFactory;

    /**
     * @param Context $context
     * @param PageFactory $resultPageFactory
     */
    public function __construct(Context $context, PageFactory $resultPageFactory)
    {
        $this->resultPageFactory = $resultPageFactory;
        parent::__construct($context);
    }

    /**
     * @return \Magento\Framework\Controller\ResultInterface
     */
    public function execute()
    {
        /** @var \Magento\Backend\Model\View\Result\Page $resultPage */
        $resultPage = $this->resultPageFactory->create();
        $resultPage->setActiveMenu('MageDirect_Faq::faqs')
                ->getConfig()->getTitle()->prepend(__('Faqs'));
        return $resultPage;
    }

}

<?php

// app/code/[VendorName]/[ModuleName]/Controller/Adminhtml/Faq/Index.php

namespace Magedirect\Faq\Controller\Adminhtml\Faq;

use Magento\Backend\App\Action\Context;

use Magento\Framework\View\Result\PageFactory;

class Index extends \Magento\Backend\App\Action

{

/**

* Authorization level of a basic admin session

* @see _isAllowed()

const ADMIN_RESOURCE = 'MageDirect_Faq::faq';

/**

* @var PageFactory

protected $resultPageFactory;

/**

* @param Context $context

* @param PageFactory $resultPageFactory

public function __construct(Context $context, PageFactory $resultPageFactory)

{

$this->resultPageFactory = $resultPageFactory;

parent::__construct($context);

}

/**

* @return \Magento\Framework\Controller\ResultInterface

public function execute()

{

/** @var \Magento\Backend\Model\View\Result\Page $resultPage */

$resultPage = $this->resultPageFactory->create();

$resultPage->setActiveMenu('MageDirect_Faq::faqs')

->getConfig()->getTitle()->prepend(__('Faqs'));

return $resultPage;

}

Clean cache

Clean cache and we will see the new empty page in the admin panel:

 <span style="font-weight: 400;">php bin/magento cache:clean</span>

1	<span style="font-weight: 400;">php bin/magento cache:clean</span>

Now we can add a simple grid to this page by using UI Component. Let’s do it.

Сreate layout file

<!-- app/code/[VendorName]/[ModuleName]/view/adminhtml/layout/faq_faq_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">
            <uiComponent name="faq_listing"/>
        </referenceContainer>
    </body>
</page>

<?xml version="1.0"?>

<body>

</referenceContainer>

</body>

</page>

Our UI Component will have a name faq_listing.

Create faq_listing.xml

Create faq_listing.xml inside ui_component folder:

<!-- app/code/[VendorName]/[ModuleName]/view/adminhtml/ui_component/faq_listing.xml -->

<?xml version="1.0" encoding="UTF-8"?>
<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">

Add the class

It is important to add the class that is responsible for preparing data for the grid (faq_listing_data_source):
