Hello,
we are not sure what this would exactly be called, but its on the FAQs section of most websites; when the question is listed and once the button is clicked it opens up and shows more information?
for example the questions would be
1) what color is the sky
and once clicked, it opens a “panel” underneath which says
the sky is blue
we have also added a domain on the PCA which shows this example.
thanks for your help!
