Is it possible to enable auto play for a YouTube video in the new Webflow lightbox, even if passing on YouTube parameters through the URL doesn't work?

Yes, it is possible to enable auto play for a YouTube video in the new Webflow lightbox, even if passing on YouTube parameters through the URL doesn't work. Here's a step-by-step guide on how to achieve this:

1. Add a Link Block or a Button in your Webflow project where you want to open the lightbox.

2. Give the Link Block or Button a unique class name. For example, you can name it "lightbox-trigger".

3. Create a new Interaction for the class "lightbox-trigger". You can do this by going to the Interactions panel, clicking on the "+" button, and selecting "New Interaction".

4. In the new Interaction, select the trigger type as "Click". Then, choose the action type as "Open Lightbox".

5. After selecting "Open Lightbox", you will see a Lightbox Settings panel on the right-hand side. In this panel, you can add or select an existing lightbox to connect with the trigger.

6. In the Lightbox Settings panel, you will find an option called "Video". Click on it, and then choose the source as "YouTube".

7. In the YouTube settings, you can now add an embed URL for the video. However, passing on YouTube parameters through the URL might not work in this case.

8. To enable auto play for the video, we need to add custom code. Go to the site settings, and click on the Custom Code tab.

9. In the Custom Code tab, you will see two sections: Head Code and Body Code. We need to add the code in the Before Body End tag section.

10. The code we need to add is JavaScript code. Here's an example of how the code should look:

```javascript

```

11. Once you've added the code in the Before Body End tag section, save your project and publish it.

With this setup, when a user clicks on the Link Block or Button with the class "lightbox-trigger", the lightbox will open with the YouTube video embedded. The JavaScript code we added will automatically add the "autoplay=1" parameter to the embed URL, enabling auto play for the video.

Please note that this method uses custom code and may not be officially supported by Webflow. Ensure you test it thoroughly to make sure it works as expected in your project.
