How to click a button 'VIEW MORE' to open up a new hidden section underneath

Hello, 

I have a website where my client wants me to show 6 events, and then a 'VIEW MORE' button. The view more button when pressed should open up the section immediately below it. Until the button is pressed, I'd like this section to stay hidden. We are on the business plan. 

Please could anyone help me?

Thank you so much!

I used to help this for a member on forum (I can't find that thread) but if you share page url, I can check & give you code

Page url above doesn't exist now

Thank you so much, I followed the link and membership for Will Myers and that fixed exactly what I need! 🙂
