Steps to reproduce

我将web应用嵌入到html页面中，不能显示标题栏，而F12以后，却可以看到蓝色的标题栏目。缺少标题栏，用户无法重置对话。

✔️ Expected Behavior

正常应该显示标题栏目，或者是可以提供一个会话重置的按钮连接。

❌ Actual Behavior

web应用中，无法显示标题栏。

Hi @futureflare You should adhere to "I confirm that I am using English to submit this report (我已阅读并同意 https://github.com/langgenius/dify/issues/1542)." So everyone can understand this.

你好, @futureflare ，你应该坚持 https://github.com/langgenius/dify/issues/1542 这样每个人都能理解

That behavior is expected, the header will only show if the window width is less than 640px, if is more is going to return null. So I'm guessing that you are using the first way to embed the frame:

这种行为是预期的，标题栏只会在窗口宽度小于640像素时显示，如果宽度大于640像素，则会返回null。所以我猜你正在使用第一种方式嵌入框架。

To address the issue of the title bar not displaying in your web application embedded via an iframe, and to implement a conversation reset functionality, you'll need to consider a couple of technical strategies.

1. Visibility of the Title Bar: The behavior you're experiencing, where the title bar only appears under certain conditions (like when inspecting with F12), suggests that there might be CSS or JavaScript conditions affecting its visibility. Since the title bar's visibility is expected to change based on the window width (appearing only when the window width is less than 640px), ensure your embedding setup doesn't inadvertently keep the iframe's width above this threshold, thus hiding the title bar. If necessary, adjust the CSS or JavaScript logic that controls the iframe or the embedded application to ensure the title bar is visible when needed.

2. Conversation Reset Functionality: To enable a conversation reset button or functionality from outside the iframe (in the parent document), you can use the postMessage API for cross-document communication. Here's a brief overview of how you might implement this:

   • Inside the iframe (Dify application): Add an event listener that listens for a specific message, such as 'RESET_CONVERSATION'. Upon receiving this message, trigger the logic to reset the conversation. This involves updating the application's state to reflect a new or reset conversation.

   window.addEventListener('message', (event) => {
     if (event.origin !== "EXPECTED_ORIGIN") return; // Replace EXPECTED_ORIGIN with your domain
   
     if (event.data.type === 'RESET_CONVERSATION') {
       // Logic to reset the conversation
     }
   });
   

   • In the parent document: Send a message to the iframe to initiate the reset. This can be triggered by a button click or another event in the parent document.

   const iframe = document.getElementById('difyIframe'); // Ensure the iframe has an ID
   iframe.contentWindow.postMessage({ type: 'RESET_CONVERSATION' }, '*'); // Adjust target origin as needed
   

Ensure you replace "EXPECTED_ORIGIN" with the actual origin of your iframe content to secure the communication. Also, adjust the postMessage target origin from '*' to the specific origin of the iframe for enhanced security.

This approach allows you to maintain the functionality and appearance of your embedded application, ensuring users can see the title bar when necessary and reset conversations as needed.
