Create submenu blogs

Hi again :)

There’s another question.

My mainpage is the blog of the website (full width 3 columns grid / every categories).
I’m looking to have 5 menus, with each displaying a blog of a single category (simple layout, one column on left, sidebar on right), with pagination.

Here is my question : how can I create these one category blog ? I’m trying to add the “Recent blog posts” shortcode in visual composer, but I can’t get the full loop of articles (only like “display 4 posts”).

Hope I made myself clear…
Thanks !
