Collapse/Accordion post listings??

Hi there.
I’ve been searching around for ages but haven’t been able to find a solution for this request.
Does anyone know of any plugins or hacks that would allow blog posts to be displayed purely as heading until it was clicked on. When clicked, the post content would appear/expand vertically instead of going to an entirely new page.
I guess something like this but “nicer”: https://www.tomato.co.uk/
Any help would be greatly appreciated.
Cheers
