Front end editor and tabs

I’m working on a website where selected people can edit a post on the front end. On the pages I have tabs/accordion to organize the content by years.

So, this year they have to edit the 2015 part, and next year the 2016 part, and so on. I’ve tried al lot of front end editor, some work great but didn’t work with the tabs/accordion. It’s very important that they can easily edit, because they don’t have skills of WordPress or HTML.

What is the best to do this? Maybe you have some tips about organize the content on an other way. I thought about put all the content above each other, but that will be to much. Maybe you know a good plugin.

Thanks!
