Indeed, it works just fine! and the read more trigger disappears, acting like a true ‘read more’ button, rather than a toggle element.
Using CSS, you can also style it to look exactly like a button… CSS provided below to get the same look as the button you clicked.
This one is like the regular toggle element, but the toggle text stays above the button, acting closer to a proper ‘read more’ and ‘read less’ button.
