Is it possible to create my FAQ's page with drop-down answers?

I have added a text box to my FAQ's (Frequently Asked Questions) page; and added questions with answers. Is it possible to re-create my page with questions with an arrow for drop-down answers? Or maybe it's just not possible without the assistance of a website specialist. Thank you for any advice. Please view my website https://www.juliemyerscelebrant.com.au/
