Hi DEEPAK,
Sorry for the inconvenience.
However, this is just a static HTML template and we have just shown there the design & preload effect, how it will look like when someone click on the next button. We don’t use any tab there.
The idea is, there will show the latest posts by default. When someone click on the next button, then it will show older posts with a preload effect, that’s it. In this issue, you need to convert the template with PHP or WordPress to make it works dynamically.
Thanks for your understanding.
Best Regards,
