Is there a way to have a text box that expands when you click more/ a plus sign?

hey people. hope you're all staying safe in these times. I have a website where the person wants to include an FAQ section. and where there question is on a line. They want there to be a Plus sin or a click for more button that will show the answer to the Question Similar to https://www.themusclementors.co.uk/coaching if you look at the 3rd section up from the bottom (not including the footer) Is this possible to do in square space or via a widget?

I appreciate your help
