When you enable post communication you can read elements from the iframe and transfer it to the parent and include it there. This is like the feature "Include content directly" from the "Add files/content" from the next tab but more powerful. You can define here as many elements you like and insert it to the parent page. To enable this setting you need to specify the element of the parent and the element of the iframe separated by a |. Several settings are separated by , e.g. #c-id|#content,#s-id|#some-images,#p-id|#iframe-right p:nth-child(2). You can use any valid <a class="jquery-help-link" href="#">jQuery selector pattern</a> here! Please read the section "<a class="howto-id-link" href="#">How to find the id and the attributes</a>" to find the right id or class. Currently, the iframe is NOT hidden by default. After the setup you need to set display:none; on the basic tab at "Style". Currently, there are no additional settings like for the same domain. So make sure that e.g. the divs you want to add the content have e.g. the correct height for optimal display! <br><strong>Important</strong>: For security reasons, you must configure this feature in both ai_external.js and the plugin starting with version 2026.0. You can do this by configuring everything here, or by setting it in the shortcode with data_post_message="". AND configuring it with <a href="#mirp" class="link-id-external-ai-overview">dataPostMessage</a>. The plugin removes <script> tags from HTML content to help prevent XSS (Cross-Site Scripting) attacks.
