Your readers will be also able to read more content by pressing the ‘Read More’ button, without having the page reloaded.
Once you press “Read more” button, it will expand.
They will also be able to hide it again by pressing the same button, which would have been converted to ‘Read less’.
It works via a shortcode and can be placed everywhere!
