how to use true tinymce editor in magento2 and how to fix it? Many thanks


It is better not to insert that block of code directly into HTML template file, but to use Magento native way to embed field:

    'full_content', 'editor', array(
        'label'    => __('Full Content'),
        'required' => true,
        'config'    => $this->config->getConfig(),
        'name'     => 'full_content',

To make this work you also need to add dependency into the constructor:

 * @var \Magento\Cms\Model\Wysiwyg\Config
protected $config; // <-- add this variable inside the class

public function __construct(
    \Magento\Backend\Block\Template\Context $context,
    \Magento\Framework\Registry $registry,
    \Magento\Framework\Data\FormFactory $formFactory,
    \Magento\Cms\Model\Wysiwyg\Config $config, // <-- this new line
    array $data
) {
    parent::__construct($context, $registry, $formFactory, $data);
    $this->config = $config; // <-- and this new line
