Tab within category page

I’ve a website where I use categories in my menu, so to display the posts for each category in one specific place that corresponds to the category itself.

Here is the page

As you see, each item/sunglass is a post, which belongs to the category Cellulose acetate, and on top of all those items, I’d like to have 2 tabs: one for the items, and one that would make the items disappear and instead display some text.

Is there a way create a menu/visual editor of the category’s pages, or any other way to obtain the result I’m looking for?

Thanks a lot, any help is highly appreciated 🙂
