I was having the same issue like the content was showing just below the tab name.

enter image description here

Creating Form.php inside Vendor/Module/Block/Adminhtml/Faq/Edit/Form.php helped me solved my issue. after creating Form.php:

enter image description here

enter image description here


Here's a complete structure which I followed:

  1. Admin layout xml file:

    <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="../../../../../../
    ../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
        <body>
            <referenceContainer name="left">
                <block class="Invigorate\ProductQuestions\Block\Adminhtml\Faq\Edit\Tabs"
                    name="invigorate_productquestions_faq.edit.tabs"/>
            </referenceContainer>
            <referenceContainer name="content">
                <block class="Invigorate\ProductQuestions\Block\Adminhtml\Faq\Edit"
                    name="invigorate_productquestions_faq.edit"/>
            </referenceContainer>
        </body>
    </page>
    
  2. Now create Vendor/Module/Block/Adminhtml/Faq/Edit/Tabs.php

    <?php
    
    namespace Invigorate\ProductQuestions\Block\Adminhtml\Faq\Edit;
    
    use Magento\Backend\Block\Widget\Tabs as WidgetTabs;
    
    class Tabs extends WidgetTabs
    {
        protected function _construct()
        {
            parent::_construct();
            $this->setId('faq_edit_tabs');
            $this->setDestElementId('edit_form');
            $this->setTitle(__('FAQ Information'));
        }
        protected function _beforeToHtml()
        {
            $this->addTab(
                'faq_info',
                [
                    'label' => __('Editing Record'),
                    'title' => __('Editing Record'),
                    'content' => 'Editing record fields',//Change this to your block layout as per your need.
                    'active' => true
                ]
            );
            $this->addTab(
                'faq_products',
                [
                    'label' => __('Products'),
                    'title' => __('Products'),
                    'content' => 'Products Block',//Change this to your block layout as per your need.
                    'active' => false
                ]
            );
            return parent::_beforeToHtml();
        }
    }
    
  3. Vendor/Module/Block/Adminhtml/Faq/Edit.php

    <?php
    namespace Invigorate\ProductQuestions\Block\Adminhtml\Faq;
    use Magento\Backend\Block\Widget\Form\Container;
    use Magento\Backend\Block\Widget\Context;
    use Magento\Framework\Registry;
    
    class Edit extends Container
    {
        protected $_coreRegistry = null;
        public function __construct(
            Context $context,
            Registry $registry,
            array $data = []
        ) {
            $this->_coreRegistry = $registry;
            parent::__construct($context, $data);
        }
        protected function _construct()
        {
            $this->_objectId = 'id';
            $this->_controller = 'adminhtml_faq';
            $this->_blockGroup = 'Invigorate_ProductQuestions';
    
            parent::_construct();
        }
        protected function _prepareLayout()
        {
            $this->_formScripts[] = "
                function toggleEditor() {
                    if (tinyMCE.getInstanceById('post_content') == null) {
                        tinyMCE.execCommand('mceAddControl', false, 'post_content');
                    } else {
                        tinyMCE.execCommand('mceRemoveControl', false, 'post_content');
                    }
                };
            ";
            return parent::_prepareLayout();
        }
    }
    
  4. Now create Form.php inside Vendor/Module/Block/Adminhtml/Faq/Edit/Form.php

    <?php
    namespace Invigorate\ProductQuestions\Block\Adminhtml\Faq\Edit;
    use Magento\Backend\Block\Widget\Form\Generic;
    class Form extends Generic
    {
        protected function _prepareForm()
        {
            $form = $this->_formFactory->create(
                [
                    'data' => [
                        'id'    => 'edit_form',
                        'action' => $this->getData('action'),
                        'method' => 'post'
                    ]
                ]
            );
            $form->setUseContainer(true);
            $this->setForm($form);
            return parent::_prepareForm();
        }
    }
    

Note: Please change Vendor, Module and other necessary names as per your need and you're good to go. and inside Tabs.php inside Tab content mentioned your block and replace static content string.

I hope this will help you, Thank you :)
