Blog posts shown in an accordion

Hello! I hope I will be able to express what I am trying to achieve :) My client’s website will have tag pages that collect entire blog posts with a certain tag. As the blog posts will be A LOT, we would like to show them in a horizontal accordion, but with a bit of the article shown to understand what you are going to read if you open that tab.

a bit like the third example here http://qapoint.es/elements/accordion-slider/ but horizontal and with just “open/close” state (not with on hover) – very similar to the accordion we can have on enfold.

I am sending you a couple of screenshot to let you understand.

Thanks in advance!
