Tell us what you are trying to do?
Create a YouTube Video Post Type and Grid Gallery using Views that displays the YouTube poster image BUT, doesn't load all the YouTube http calls until a vid poster/post thumbnail is clicked.
Is there any documentation that you are following?
Noe to be found
Is there a similar example that we can see?
Yes BUT, the difference is I will be creating a video custom post type and not using a YouTube channel feed. Here's an example made with the Essential Grid plugin: hidden link
What is the link to your site?
Unfortunately, I'm building it on my local host but: hidden link
Unfortunately such a feature isn't available in views by default however if essential grid provides a way to send the data to it to create this then it would be possible.
Since your videos would be stored in a custom field I would highly advised contacting the essential grid team to see how best you can provide data to their grid .
With views only you won't be able to achieve this.
